I've got a Saitek eclipse as well and normally swear by it. It's a great keyboard and has done me proud for a while now, but I won a Razer Lycosa at the last LAN and I'm testing that out. So far it's also been good
I've had a Razer Copperhead now since they were launched and I've haven't found a better mouse yet. My Bro-in-law won a Razer Lachesis at the same LAN, and he's having a look at that 4000 dpi
If he doesn't like it he might chuck it my way.
I've got a func 1030 mouse mat and that also rocks, it's got a smooth side and a rough side, they do make a slight difference, but not that you'd notice much.
I reckon whatever suits you best, it took me a long time to get used to the new Copperhead, but now I can't live without it. Try a few mates setups, or go to a LAN and try everyones, until you find what suits you best.
