I have a g7 in great condition, has just been reconditioned and cleaned inside and out. works very well and has box and cd and everything that came with it, $40neg + p&h.
An unreal gaming mouse although i recomend highly on the purchase of a gaming mouse pad for stability of the lazer.
Specs and info are available here, you should know that the rrp is roughly $88.00 and not the price on the link below although that is what was paid for it
