My faithful MX510 is beginning to have click problems, so I need to replace it. I once read that the MX518 was the last gaming mouse that didn't have built-in lag because of an onboard processor, or something like that. Apparently the MX518 is so rare now, just look at that price! I'm not prepared to buy a used mouse.
So, what's the best wired (I don't want extra lag and battery weight) gaming mouse these days that doesn't have any built-in lag? Is what I read BS? I mostly play FPS and Rift, and I'll need to use the mouse in linux. I don't care about linux software support — as long as every button is recognised by X, I can map them. Should I get the G502? Reluctant to pay more than like £80.

] better than usual. It works surprisingly well in Linux, despite the Logitech software not supporting it there. Because of that, if you want to reconfigure it, it'll have to be done in Microsoft's Windows. It can remember the settings, so they'll work in Linux. For example, I had a game of Xonotic in Linux and was able to use the settings I had configured in Windows to change DPI in-game.
