Hello - I was wondering if anyone had any thoughts on Wacom Tablets. I am specifically looking into the bamboo based on price (I've found it in the $50 price range). I've never used a tablet before so I am leary to spend a ton of money on one since I do not know how frequently I will be using it for photography and graphic design purposes. I do not know a lot about the technical aspects and interface so any advice would be GREATLY appreciated. Thank you!
