I have just enrolled in a Photoshop class at my college and I am in need of a mouse. I have Photoshop CS5 on my MBP and I have used the trackpad for somethings, but I feel it would be to difficult to use for the more complicated/precision tasks in PS. I ask you for your personal preferences for wireless mice (USB receiver or Bluetooth). I'm looking to keep it on the cheaper end of the price range as paying for school has done quite a number on my bank account already. I've used MROOGLE, but all the threads seem to be older. Thanks for all your help. EDIT: I'm left-handed, so no mice curved for righties.
