Are there any good recommendations for incredibly smooth mousepads? I don't want a hard pad, so something like an Icemat is out of the picture. I also want a large pad, as I'm always hitting the edge of my pad even with my insanely high sensitivity (<10cm/360 with a bit of accel).

My price range is pretty much <$50, preferably including shipping.

I'm looking at the Zowie G-TF Speed. Thoughts?
