Here's the breakdown as I see it:

Barring getting a blacksmith to make you you the real deal for thousands and thousands of dollars, the best you could do would be to buy this guy's handmade replicas: He doesn't always have ebay auctions up though, and some times his work will turn up for sale elsewhere.

EDIT: Aaron of Fiberglass Blades is stopping production so that he can move on to bigger and better things. There will be a few auctions for what remains of his inventory this year, but don't expect to pay less than $1000 a piece for each item.

If you are looking for the cheaper mass produced kinds, there are still several to pick from, and even then you need to decide if what you want is more for display or if you actually intend to carry it. None of these are combat safe in any way, but some still are better than others.

A disclaimer about these links: all of these can be found from multiple sellers at multiple prices, so do your shopping! I'm using amazon for picture purposes.

The best one for display in my opinion is this one here. The hilt and blade look fantastic, and it comes with a plaque. It is not good for swinging though; it is very heavy and is most likely not full tang, aka the blade does not continue into the hilt. That said, it is a beautiful piece for the price, and I have one on my wall. It seems to be based off of a mixture of the Link to the Past and Twilight Princess Master Sword designs, as it has barbs, but is not blue in color. There are newer versions of this same sword modeled after the blue master sword and a Dark Link Variant, but I avoided the former because I don't like how the entire handle is one shade of blue. That's your call.

Next up is this one, which is probably the most common. The blade is long, but does not have that awesome shape that the above one does. In my opinion, it does not look as much like the master sword as it ought. The upside to this though it that the sheathe is the best one going in terms of mass produced pieces. I am cosplaying as link at Otakon this weekend, and will be using the sheathe from this sword, attached to this belt that was basically made for this model.

The sword I will be using is this one. I know what you are thinking. Foam? Really? Yes. This is a relatively new product and is of far better quality than I could have expected or even hoped for. It is cosplay safe, light, and the best shape/size/detail/quality replica I have found for the price. if you plan on carrying one without getting arrested, this is the one.

There is another master sword replica out there that you need should watch out for. this one looks very similar to the second one above, but you will notice the blade looks mildly different in the photos. In truth, this one is far smaller than the above one, and is also sharp as hell. Can not recommend. Check the details like blade length and width before buying.

As for the shields, there are thankfully fewer options. As mentioned above, Fiberglassblades makes an amazing one, but it's super expensive. I'd like to own his shield and sword one day, but it will not be anytime soon.

Your mass produced choices as far as I can see are this one or this one

I have the first one, and it is a decent replica for the price. It is set to be held in your left hand, though you can remove the handle, so I expect you could modify it for more accurate use. It is also ready to be hung on a wall, and looks quite nice while doing so. Older models are more flat, while newer models are more curved like traditional shields (unless mine is just warped.) The Downsides are that the strap and handle are rather flimsy. I have reinforced the one I'm using this weekend by making my own leather strap and super gluing the handle in place. This will sadly prevent me from using this shield as a display, but I have an older model for that.

As for the second one, it looks to be a newer version of an earlier and different model. I don't have experience with it, but from what I can tell it seems to be a high quality replica. That said, the model I believe it is based on was not able to be hung on a wall, had the triforce crooked, had the bird painted on and not embossed, and could only be used in your right hand. Perhaps this is why they are pushing this new version. If you get this one, please let me know how it is, because I must say it looks good from the photos.

EDIT: Another user has reported to me that this model still has the issues I had with the earlier version. Neither the Crimson Loftwing nor the Triforce are guaranteed to be accurately placed. This may vary from shield to shield, so buyer beware.

PHEW! Hope that helps!

Craziest thing? Probs this or this

Not way crazy but I never treat myself to cool things so buying that seeems crazy to me!

I bought this one: http://www.amazon.com/gp/product/B001I87WMC/ref=oh_details_o04_s00_i00 and it's beautiful and is quite sturdy especially for your use. And only $40!

If you got 50 bucks and amazon prime you can get it! I bought the same one and my only issue was the gold bit at the top of the sheath coming out with the sword, but some super glue fixed that
