I have the SP3 and I'm looking for a good art program. I am currently using ArtRage which I really like to use for making linearts (their pen tool has an awesome smoothing feature) but I am unable to find a program that has a smudge tool (similar to the one Gimp has.) I tried Gimp but it lags (which is most likely user error) but I am also not a fan of it's eraser tool. I am also against using SAI mainly because last time I tried to get it, I got a virus. I have also tried Krita, I cannot figure out how to use it (even after looking at loads of tutorials) to save my life. I am not against paying (just please not over 60 bucks) and free is awesome also. Thank you!!!
