Thats pretty close, shape-wise to the MouseMan, which was one of my first mice.
When the MouseMan died I went to some cheapy compaq mouse, got carpal tunnel in my right hand. After realizing the cause, settled on the MX518 as others have mentioned (no carpal tunnel since). I primarily use a G500 now, but that has a horrible cable (on my second one in a little over a year). Logitech doesn't even manufacture the G500 any more; it's not listed on their site, AND doesn't have a single mouse with a similar button layout. The G502 is the closest, but is missing the top button (above the scroll wheel). I use that with AHK for various tasks (browser -> Ctrl+W)
The Logitech G700s should of been good, but the top button layout is horrible, it's nearly impossible to press the top-middle button without pushing down the scroll-wheel free-roll button. The top-left buttons require too much force, and aren't easy to choose between. The 4 thumb buttons generally aren't distinctive enough to use as Ctrl, Shift (plus 2 other functions) and accurately press the one you intended (unlike the G500's 2 thumb buttons).
