looking for best wireless gaming mouse

Keyword wireless. I want recommendations on the best wireless mouse to use for gaming.

Reason I need wireless is I have my comp hooked up to my TV, I sit 8 ft away.

I was thinking the logitech G7, it had up and down reviews. I don't know if thats because its mediocre, or because people are just expecting too much.

what do you think would be a good mouse to game with wirelessly.

ok, so what kind of USB extension would work. Does the fact that something like the G5 says "full speed USB"? Is that just a fancy term for USB 2.0, so would a regular USB 2.0 extension hurt the transfer speed at all?

I use a Logitech G7

Works great, great response times

I'm playing WoW, TF2, HL2 Deathmatch, and Combat Arms

I have been looking for a wireless gaming mouse also. when I see the g-7 it is either black(carbon fiber look) or green. I also have never seen both of them at the same site. I feel one is probably an older model.
Is there a difference?
I did try google but came up empty.

I use the logitech G7

i had a G7 mouse for almost 2 months and then it suddenly started cutting out for 5 seconds every 30 seconds. i updated/reinstalled/swapped usb ports but no change. its one of the reasons why logitech discontinued the G7 mice, because its a lottery when you buy one.

but yeah, before it broke it was the best mouse i've ever used
