I use a Wacom Intuos Touch, would have to dig it out from under paperwork to double check if it was actually the large or medium model, but it is honestly bigger than I really need for photo work.
Several of my friends have Huion tablets that they're exceedingly happy with, and very happy with the extra cash left in their wallet over the premium paid for a Wacom. If my Wacom dies, I expect I will likely replace it with a less expensive competitor as I don't really get enough daily use out of it to justify the premium price.
