New Laser Mouse (advise)

I'm thinking of buying a new mouse as my old Microsoft explorer 2.0 has started to perform poorly. I had a look at some Logitech mice today and I came accross this one:

Now I'm not specialized in this and so would like some advice. I like the design and the laser capability of the one I linked above but didn't really have time to examine others.
I'm not necessarily looking for a game mouse with thousands of buttons on it but a good response time one to work on my wood surfaced desk.
Also, it MUST to be wireless and would prefer laser as it's more precise.

Any advise please?

 

It looks nice, only thing a lot of people look for in cordless mice is the batteries - the fact that they take AA batteries means they'll need replacing more often whereas if you got, say an MX1000, it has a charging cradle so doesn't require you to replace the batteries.

Just a thought....
