Do you have a specific budget? Mice like the R.A.T. 7 can be extended to fit any size of hands, have interchangeable palm rests for better grip or higher stand, have interchangeable pinkie rests, have weights you can add, and are built on a solid, thick, metal base. I personally own a R.A.T. 7, R.A.T. 9, Logitech G600, and a couple other mice, I'm very pleased with the 7, only drawback, if used on a laptop, you'll have a lot of extra cabling. The RAT 9 is also good, but I've read that some people have issues with the connectivity since it's wireless, I never experienced that.
