I have no experience with these but I wanna try as using a mouse during hours is not comfortable at all, at least for me. I saw some in 30-40 range by Logitec or Kensington non-wireless. I guess they're not 'super awesome' but unless someone here tells me that's pure shit, I'd tend to buy one. What do I have to now before buying one? I mean there's certainly something recommanded or not to use with pro tools on a mac.
