Tomshardware reviewed several gaming pads recently and the xray's came out on top.
The review here is on a bigger pad, The Thunder9 by xraypad, which works well for you low sensitivity folks like myself.

If you like a smaller pad take a look at this review of the Thunder8:

Or for those that just want a decent pad that's very big for low sensitivity users and very inexpensive, just grab yourself a Supermat. You can find them at microcenter and comp usa or from an online retailer. There only about 8 bucks now and they are 17 1/2" x 13 7/8".
They are the same pad as the famouse fatal1ty pad without his logo and the additional $15.00 for his ego.
