Since I started playing UO:
2 Regular Keyboards - I now run an "old school" G-15 with all the keys down the left side and have a new in the box spare in the closet for if/when this one dies.
8 mice -
2-1 old school plain ol mouse, one track-ball mouse - neither good for gaming applications.
2-Razers (1 Adder and 1 Copperhead) found that I HATE RAZER's so much that I won't even touch one now even if it was free.
2-Microsoft gaming mice (both SUCKED so bad that they lost their tails within days)
2-Logitech gaming mice - 1st was a MX 518 that was ok, however, didn't like getting its tail pulled on. 2nd was and still is my all time favorite gaming mouse - the G5 Lazer mouse. I'm on my 2nd one of these, due to wearing out the first ones *left clicker.
