Looking for a cheap(er) gaming mouse?

I'd prefer to spend no more than around $25 but I'd spend a little bit more if it be worth it. I don't really feel like I "need" a gaming mouse, but I think it'd be cool to have, and the side buttons might come in handy. So far I've looked at this Gigabyte one the most:
http://www.amazon.com/Gigabyte-High-Definition-Optical-...

but I've also heard that these ones are really good as well, just not to fond of the lights: http://www.amazon.com/Cobra-E-3lue-Precision-Control-16...

Then I've also looked at the Logitec G400, but that's a little bit more than I'd like to spend and I'm not sure if it'd be worth the extra $20 over the Gigabyte. Anyone else have any that I should look at? The two I linked are from Amazon, but I'll order from newegg or tigerdirect if they have better prices or something in stock that amazon doesn't, Amazon is usually cheaper for things that aren't computer hardware.
