Manga Studio Brush Sets Worth Considering

I just spent money on some cool brushes for Manga Studio 5 (aka Clip Studio 5), so I want to use them before I buy more. I want to see if they are actually going to help me create art before investing in stuff just because it's new and exciting.

That being said, I did find some other cool brushes out there while I was shopping, so I have decided to list them here so I can come back and get them later.

• Deviant Art Listing: Just a cool list of brushes, including many of those listed below.
• Manga Studio 5 300+ Brush Super Set by Frenden: This set is $15, so I'll need to look it over closely before purchasing.
• Comic Book Inkers Set 3 (not the official title, but I chose this name because it has pens named after Kirby, Sinnot, Mobius and Wood. I think this includes Flashtools for Manga Studio and Clip Studio Paint: Cost $5.50
