I have to agree, Painter is a pain and has so many flaws that I wouldnt pay money for it again. I have tried the demos on both Zbrush and Deep Paint 3D and I really liked the way both of them work. Sadly I am not independently wealthy and can not afford those two programs. I would definitely reccomend you download the demo versions of both Deep Paint and ZBrush and give them a try. They work fully as far as I could tell, I just wish the 30 day trial was a little longer.
