Wow, thanks guys. I really appreciate the advice.
The Molten and the Naga Epic (or even the Star Wars version of the epic) all look pretty great. I'm torn between them. The G700 looks a little simple but my current mouse is an old G5 which, I have to admit, has served me really well for about four years now, which I think is impressive. I'm hoping for something really suited to gaming now, for TOR and soon Diablo 3, (the SteelSeries Diablo 3 mouse is awesome but too simple for MMO games), so it's a little difficult to decide. Most of the issues that people seem to have with any mouse seems to be related to size and them being too small for their hands. I do not have very large hands and so I would not share those problems, I suspect. As such, I do not think the Nostromo would be good for me at all. And that R.A.T. 7 just looks way too intense and intimidating to me. Whoa! Hehe.
So I guess maybe I'll consider the Molten or the Nage Epic.... Maybe also keep my eyes on that R.A.T. 7 as well. Thanks again for the advice.
