Well, the first thing you want to do when getting back into drawing is grab a sketchbook. I say this because you want to get your drawing skills back up to par naturally before going digital. Once that is done, which shouldn't take too long (Just take time to sketch everyday), head over to Wacom.com. Order a Bamboo, which I believe is about $100, and you'll be set. In my opinion, it's not going to help pixel work that much if you're working pixel-to-pixel. But if you want to get into digital art, definitely grab yourself a tablet.
