In the past, Microsoft used to make the Wheel Mouse Optical 1.1a... a comfortable mouse that was never marketed as a gaming mouse but it turned out to be arguably the best mouse for gaming at the time.
It is now impossible to find a WMO ANYWHERE new... it was discontinued ages ago must be 6 years or more since I last saw a WMO on the UK high street... my old one has broke after 10 years of usage and I regret not getting a few more while they were still available.
It seems that the WMO has been replaced by the Basic Optical v2.0 and as far as I can gather from the data sheet supplied by Microsoft it would seem that this is the direct descendant of the WMO 1.1a... though I MAY be wrong.
It certainly seems so because if you compare the data sheets:
