Either my PS/2 MS IntelliMouse 1.1A (a plain 2-button MS Mouse came with my 1994 Gateway 2000 P-90, but after a few RMA's just before the 3-year warranty ran out, they sent this one instead) or my Sony GDM-400PS 19" monitor. The mouse has lasted me 3 years already, and I don't know of anything else that is as good (to me) for gaming, control, and feel except maybe the IntelliMouse Pro (discontinued). I purchased the monitor (for $555 shipped) at the end of last summer and it's a great upgrade from 15" (which I used from 1994 to 1999) and from 17" (which I used for 3/4 year in 1999). I was also considering the Hitach Superscan 751 19", but I paid $80 more for the Sony because I simply HAD to have the Active Signal Correction button 🙂
