Logitech's G502 is our favorite heavy gaming mouse and it's on sale on Amazon for only $38.75 right now. That's about as cheap as it gets for a quality rodent.
The version that's on sale is the G502 Proteus Spectrum RGB, not the newer Hero model with an upgraded sensor. That's not a deal killer though, especially at this price—the PMW3366 sensor inside the Proteus Spectrum is still very good, offering a 300-12,000 dpi range. That's way more than is needed.
I made the upgrade to this mouse myself several months back and don't have any regrets. It comes with a set of five 3.6g weights, so you can make it heavy or light depending on your preference, and also adjust the weight balance.
Other features include 11 programmable buttons, a hyper-fast scroll wheel, and of course RGB lighting.
