Best computer tablet for art?

Who here has bought tablets for drawing digitally? I'm looking for something inexpensive (under $100), preferably that will work with the program GIMP. I've be scouring the internet but there's like a million tablets out there!

I've used Wacom products for the last 8 years and highly recommend them.

Good quality stuff. A few of my friends who do a lot of digital art use the Wacom Intuos.
I've had 2 Graphires, but their Intuos lines are highly recommended.
Their Graphire line has been replaced with their newer Bamboo line.

Wacom user here!
I typically use a Wacom Bamboo Splash in conjunction with Paint Tool SAI. I got mine for around $80[they typically range from $60 to $90 depending on the retailer]. It should work with basically any art program out there [GIMP, Photoshop, Corel, the aforementioned SAI, etc].
