Hmm. I don't know. Sounds like you could use almost any mouse made nowadays. I'd steer clear of Razer in general, their quality control hasn't been great in the past.
I'd go for an optical sensor since they tend to be lower DPI (more settings at the lower end) and more accurate than laser.
Maybe try a Logitech M500? It's wired, seems to have the thumb buttons in a sensible place and looks like it may fit the hand something like the original Intellimouse.
