those mouse bungees are a bif of a gimick in my oppinion, the wrist rests arent though. my mouse cord never 'snags' i'll post a pic of why tomorrow
I've used both a Ratpad and a 3M precision mousing surface (from Staples). I personally like the 3M better, although I can see how people may prefer the Ratpad. They're both really nice, just a matter of how you want it to feel. The 3M gives a little more feedback but is still smooth. Only problem is that the 3M pads tend to bend up a little down the inside edges. It's kinda hard to describe, so imagine you're looking from the front at the pad over the surface of the desk, it'd be shaped like a gentle hill.
You can get the 3M pad from PC World - or at least, I have in the past. I'm currently using a Ratpad, and favour it over the 3M when using my MS Intelli Mouse Explorer..
