I am moving my MX518 to another rig and have settled on replacing it with a Logitech G500. The best price I've found for one is $52 shipped. Considered buying Fits' G9x but I like the MX518/G500 shape and the on-the-fly adjustable dpi. Am open to other suggestions that you think would work well for me. Anyone know if there are certain revisions/versions I should look for and if so, how to identify them? Stipulations · I couldn't care less how it looks · Must have zero functional flaws Shipping is to 55342 and there's no rush. Just looking to see if anyone has one they'd be willing to sell cheaper than I can find elsewhere. Can pay via PayPal immediately.
