Well if you are serious about making GFX get Photoshop 7, if you just want to play around get Paint Shop Pro 7.
Anyways off-topic.
I do not think Ryoko is the best here. Not even close, Orion is better then him and not to mention Nazghul is better then both of them, plus I've seen MANY very good Sig makers aroudn here (the week leading up to my banning and my return)
Ryoko is good don't get me wrong, betetr then I'll ever be, but no one here is the best. Megasaxon is very good to.
*edit* to the dude who said they were equal, I do not think so.... They are very different in style and baisicly everything else about them. Koblano is good but not the best.
