If you can get it "on the cheap" then go for it. The full version of Painter3D (notSE) is a very good painting program in it's own right & is similar in function to Painter 5.0. It includes layers (floaters) which are great to paint on & "nudge" into position on your model. Also has a great variety of paper textures (rice paper, crackles, pavement, eggshell etc.) which make for nice bump maps. Terrific amount of art brushes, filters, image hose nozzels etc. There is a steep learning curve to it as there are so many options. Also, it is much easier to create your base texture map in UVMapper & use that to apply as an "existing" texture map to your imported model instead of trying to create it within Painter. The problem with UVWrapping (as Jaager pointed out) can be solved by creating masked selections to paint within. That way you won't paint over a hand that may lay between the front & back of the torso. Or, you could create a seperate layer for each "front & back" for each part & and paint upon that layer. I.E., make a new layer with just the front & back for the head only etc.
