you guys should all check out monoprice.. they're re-branded UC Logic tablets and for under 100$ (for the biggest size, mine was 50$). i like the feel of it better than my 200$ bamboo create tablet - i draw with it on my lap and it always felt a little to light for my taste.
the only thing i would recommend if you go with a monoprice is to buy their other pen, the bamboo create pen has a nice slim profile (used to drawing with a pencil here) and the stock pen for the monoprice is kind of huge for my small hands. and considering you can get a 48 pack of batteries from a bargain store for 6$ (less in the states?) it's worth it, my pen hasn't run out of battery yet.
also paint tool sai, amazing program (abandonware) but still with the 58$ you'll throw down for it. there are only a few things PS does that i wish SAI could do too, but it does lineart like a boss :P
