The 518 is very much like my MX1000 cordless laser, but missing one button on the side.
I took a G7 back after two weeks, because I simply liked my MX1000 a bit better...couldn't tell any difference in effective resolution, I missed the missing TWO buttons on the side, and the swappable battery pack, while a damned good idea, didn't help me much because I already had two MX1000's, and just swapped one out for the other if I forgot to charge the battery. As far as the weights, the weight I liked was (surprise) roughly the same weight as my MX1000.
That said, if I didn't already have the MX1000's, and they were no longer being made, the G7 would be my choice (I freakin' hate corded mice, haven't owned one in years..hell, for that matter, my KB and joystick are cordless too).
