I have really wanted that Steelseries WoW Gaming Mouse lately, but nobody seems to have it in stock. Amazon.com lists a 2-4 week waiting period right now.

I mostly want it because of the 15 programmable buttons! In particular, the ability to map these buttons to keyboard keys!!!!

Does anyone know if there is a good alternative to this mouse that has the same functions? Multiple buttons that can be mapped as keyboard keys?
