I do art on my PC almost every day, and I use the SteelSeries Rival 600 (which someone on here recommended to me). I've used a lot of different ones through the years, including various Logitech and Razers, and they all had problems with jitter and skipping pixels. It was at a level that you wouldn't notice during normal gaming use, but which made doing art rather problematic.
It's only about $70, too. It's about medium sized and traditionally shaped, so it should feel good to use, as well.
