I use a tablet for 2D painting, 3D sculpting, 3D animation, compositing, and everything in between. Anyone who has tried a tablet and "didn't like it" doesn't have enough patience. They take getting used to, but they are by far superior to a point and click mouse. If you are looking for something basic yet somewhat professional, get an Intuos. They can be had for around $200 MSRP, but if you look for a deal you can get them a bit cheaper. The last tablet I bought was a smaller Intuos for my laptop and I paid $100 (it was 50% off), and so far it's my favorite tablet, and I've used about 6 different varieties.
