By personal use does it? or can you guys tell in looking at the picture?

Your only choices are not square filters or variable. Standard round ND filters work as well.

$30 bucks for those on a budget...

Or https://www.amazon.com/Filter-ND1000-Neutral-Density-Optical/dp/B073YGJ7L5 $60 for a 3 stop, a 6 stop and a 10 stop. Great for a budget shooter

And since you are on this anti square filter crusade, throwing it in as a budget option as well - https://www.amazon.com/Neewer-Complete-Filter-Kit-Cokin/dp/B00UFG6LU2/

$30 for 8 filters, and the holder... Looks like it would fit on a budget...

Try not to laugh at my extremely amateur comment here, but on amazon I see "starter" kits like these. Is this something that would be good for me to try out considering the price? A lot of the comments talk about a magenta hue being added to the photo, but I'm sure I'll be able to correct that.

I completely understand that these aren't good. And also, do you have any experience with the variable ND filters? I've read some decent reviews of ones such as this Tiffen I will link. But I'm just super worried about vignetting.
