In my experience...ahem..
I bought an acecad tablet back, when it was the only way to go... 12"x18", I also have an cheapy, type aiptek, that I bought for under $100, and it works fine for just about anything I throw at it.
The one thing that I do like about the aiptek, is the really cute little wireless mousey...
