You can get small granite surface plates for not too much money. My initial thought was blanchard ground steel.
Out of everything suggested I'd vote tungsten though, purely because it would be awesome. Stupidly expensive, and massively heavy, but I think tungsten's just neat.
If they're super smooth and you can cut them smaller you could attach sand paper to it for sharpening planes/chisels. Similar to this http://www.amazon.com/gp/aw/d/B0035Y7OPC/ref=redir_mdp_mobile/185-6928646-5477669 I could also be completely wrong and this type of granite is not smooth enough without being specifically made for this purpose.
Not terribly cheap, but this is the best. You can buy a granite tile or something similar from a big box for much cheaper, but it won't be truly flat. I have the the one I linked above and it is worth it. Can also be used as a weighted clamp!!
Went to home depot with a metal ruler and grabbed one of these. Think it was like $1.39 or something like that. You need to go there and see the flatness of the tile and the thick/thinness of the tile.
Did the scary sharp process for a little while using a multipack of sandpapers from amazon. Got some stones to do my sharpening in more durable manner, but this tile is still useful for flattening the soles of older planes I'm restoring. Recommend having a small amount of self adhesive sandpaper if you're doing the sole flattening like I am.
If you're interested in having a truly flat stone like Paul has for his shop, you might look into the ones he has like this. They are only $50ish after shipping, and $35-40 if you buy them from a local Woodriver or woodworking supply shop.
