Digital artists (or anyone with a tablet)- help please?

[tarmachan]

So I've been thinking about it for a little while, but I think (despite trying to save up for a USA holiday) that I want to use some of my xmas money to buy myself a graphics tablet. I love my marker pens, but I want to have a stab at drawing and painting digitally (it would make my problem of going outside the lines so much easier to fix).

So are there any tablets (or brands) that you can recommend?
