Wanna buy a wireless mouse

[Cool Buddy]

I can't drag a thing on my PC since morning, so thought of buying a new mouse. Since wireless mice are not very expensive, so wanted to buy a wireless one. But having used various brands at various times, my heart is stuck on a Logitech wireless.

From logitech's site I got info about those and I found out 2 model, M305 & M215. The reason I'm asking this question is, the website says that M215 is a laser mouse. For this reason i would have gone for it, but M305 has tilt wheel which has become a habit after having used a logitech PS/2 for 3 years. So wanted suggestions on advantages of laser and someone's personal opinion if you own one of these.
