hi

i loved my mx510, bút it died. no warranty.

but i dont like to pay 50euros for a new mouse, i saw these on a dutch site:

the logitech g1 optical mouse for 26E and
the mx400 for 36E

does anyone have any experience with these or a good third mouse, i like the weight of my mx510 and i'm definately looking for one in the same weightclass (i think ~100grams).

thanks
C.
