Personally I would buy either Razer or ASUS products since these are two extremely reliable companies (so is Corsair & Logitech). All my current peripherals are Razer products and I am extremely happy with their long lasting performance, build quality and software/re-programmable buttons.
I'd actually go as far to not recommend Asus mice actually!
They're quite cheap feeling, and don't have great sensors in the budget range.
Mionix are very good, and under represented, Logitech have a solid lineup, and Corsair are also nice, albeit a bit pricy!
