Can you do $30?
When my G500 died I bought a Logitech M500 as a temporary replacement. It's basically a cheaper version of the G500. The same body, but without the fancy finish. Same nice hyper-scrollwheel though, and still has three side buttons that can be programmed. The sensor isn't 100% as accurate as the G500's, but it's 90% there and doesn't have much acceleration. Additionally, it has about 1/10th of the z-axis sensing as the G500, so lifting it up to move it doesn't make your view swing all over like it does with the G500.
Logitech sent me a refurbed G500 as replacement for the one that broke, but the exterior was in worse shape, and after a week of using the low-dpi, low-z-axis M500 I can say that the M500 is better for me, and is a very badly overlooked choice as a budget gaming mouse.
