Wacom are the best - I've had one of those el-cheapo tablets and it gave me nothing but
grief. Wacom have the best drivers, the best integration the best support and are the
de facto standard
Intuos3 A5 - around 230 GBP
Intuos3 A4 - around 340 GBP
Graphire 4 Studio - around 100 GBP
I'd go for the best you can't afford if you think this might get serious and the Intuos3 A4 gets my vote. There's nothing like struggling with a mismatched graphics tablet to turn CAD into a misery.
But hey, the Graphire is a neat little thing for fooling around with.
Good luck
