I use a Razer Lachesis that I managed to salvage from the dead due to my tinkeritis. It is the third one I have owned though as the previous 2 just died but it was under warranty....
I have tried the Logitech g9x and the g500 and they are good - the g9 is kinda too small and the g500 is kinda too big...
I am kinda wanting to try the Cyborg RAT7 though as it seems like everything is just fully tweakable to satisfy my urge to feel like I'm making useful adjustments
