I have the Debut version...wish I could've saved up for the full EX Professional, but it's at least something to work with.
I do have a few gripes about it (that you can apparently do in the full version): you can't turn photos into screentones, you don't have an automatic word-bubble maker, and you don't have very many screentones. Other than that, I'm still trying to learn how to work out the program, but I've been able to draw some fairly decent art, and in color might I add. Although, to export my images in the size and definition I want them, I use the old "screencap and paste into Paint" method. It works great.
Oh yeah; and if you're going to use it, I absolutely recommend getting a tablet. I got one for $100 (you don't exactly want a cheap one) and it was well worth it.
