I'm using a Wacom Bamboo which is kindof small but if you don't need massive drawing space, it might suit your needs. It's probably the cheapest wacom you can get. Otherwise there's the bigger ones which are more expensive..um...I haven't really looked at them in great detail though. If you want to drop by a London Drugs one day and check out their computer and sofrware section, they have a pretty decent selection.

The programs that get bundled with wacoms is usually a watered down version of Paint. There might be other programs, but since I have a full version of Photoshop, I don't really bother with the bundled stuff. You might want to check out Open Canvas if you're serious about CG'ing. Cheaper than Photoshop, that's for sure.
