Hey guys. I've been using this basic Logitech Optical Mouse for an eternity. It's starting to age and the pointer goes haywire every now and then(only at the 'smooth' parts of my table). I've tried another mouse(bad scroll wheel) and it works perfectly on my desk. So, it's the mouse, indeed. So, my question is, should I get a new laser mouse? My budget is around 1k, but I can extend it to 1.5k. I think the iBall Laser Precise mouse is around 600-700, isn't it? Any other laser mice under 1.5k?(preferably cordless. I know I'm stretching it a bit too much!). Which is the cheapest cordless laser mouse anyways? If not cordless, can you suggest good wired laser mice?
