Can't remember the name of it, but i think it was the first abandoned research facility you visited in S.T.A.L.K.E.R. Damn, that place creeped me out ever more than the Ocean Hotel (Think that was the name of it) area in Vampire the Masquerade: Bloodlines.

P.S: I've had Thief: Deadly Shadows since just after it was released, but never played it much since it was damn choppy on my old computer. I guess i should give it another try on my new, beefed up rig.

I'm using a Logitech G5 myself. Works great, and you can instantly switch the sensetivity of the mouse between three different modes, preset at 400 dpi (Slow), 800 dpi (Standard) and 2000 dpi (Super Fast). You can customize those however you wish between 400 and 2000 dpi though. Using it together with a 4D Steelpad, and that combo works great.

Oh, and not to forget the weights. They did wonders for me, once i found a combination that suits me perfectly. They say the mouse has been developed together with pro gamers, and it's noticable.
