I know these things are usually pricey because this is the secret most gamers don't tell people. The Logitech G400s is probably one of the best mice on the market. It is not fancy, has no crazy LEDs, but the form factor and the fit in the hand is great. It's a little larger than most mice and the top comes up more than the others, fitting your hand nicely.
You can now get it on EBAY for a great price, no longer will you have to ask the Fry's guy when it'll be in stock again.
