You're right, odd request! Only other option is Blue Track a funky trackball type or a touchpad. Trackball or trackpad are probably the best, the mouse itself doesn't actually have to track over the uneven surface. I doubt you'd even get a much better experience with Bluetrack or a higher DPI laser mouse, but who knows! You may not want to but the cheapest options is probably a massive quality mousepad. It might be too soft though, even better might be a hardened plastic "gaming surface". What's this for? Media PC? Laptop?
