BleepingComputer.com: Mouse

Looking at the following: http://www.amazon.com/Microsoft-Wireless-Mobile-Mouse-Special/dp/B003PBTV38/ref=pd_cp_e_3

However, I am open to suggestions. I need the following requirements:

1. <$50.00
2. Portable (not too bulky)
3. Wireless

Will use for everyday tasks and some gaming, but I do not want a mouse with a fajillion buttons that I will never ever use - a couple programmable ones is fine.

Thanks for your help in advance.

Anyone got any ideas?

here is one if u like the ball wheel

here is one if u wanted to buttons
http://www.newegg.com/Product/Product.aspx?Item=N82E16826146004

but the one u suggested is good, i use a black version of that mouse a few things about it: it is small, the buttons on it even the right and left mouse buttons are completely silent like i dont even know if ive clicked sometimes and the scroll is smooth...some people like these things and some dont, but there just some stuff about the mouse u suggested, but it is a good mouse too

I would also if u have time maybe go to a Staples or Office Depot or a best buy to test out the mice they have, but dont buy from these stores especially best buy for u will be way overcharged, but it is a good idea to test the mice before u buy
