Well finally decided on my mouse! I chose the SteelSeries Rival, going to pick one up tomorrow on my way home.
I was going to pick the Mionix Naos 7000, but after comparing them there wasn't anything noticeably different to me other than it's shape and software. It also was no longer on sale, but even if it was I'd still probably pick the SteelSeries Rival. They seem to have the same finish, so the only difference I would truly feel would be shape, and the SteelSeries Rival seemed the best choice for my grip.
Thanks everyone for helping me choose my new mouse! Especially riznich48, he saved me $15, now I can go buy more booze!
Now to look into a new keyboard, possibly mechanical....
