Another option would be Aiptek, I have their ultra slim (about 5mm thick) A4 tablet, had it a year now and it works exactly the same as it did the day I got it, and at £65 a great buy! Over a thousand levels of sensitivity and you can feel them working! And 29 programmable macro keys. Lightweight is a must for me though as I lack room to have it on my desk as I have it covered in Monitors, keyboards and my scanner, so it's great for moveability, take it anywhere and don't notice the weight in a bag etc. Saying all that I'd love a Wacom, I know they are better overall, but I'm quite happy to wait til my one's on it's last legs to get one.
