New Mouse?

Hey, I've currently got a Logitch M510. I love the feel love it, the shape and everything are perfect. But I'm not in love with the wireless part, is there any afford able alternative to the oni have with a smiliar design? (I bought some gigabyte mouse, but the back end extends too far back and hits my palm and that bothers me a lot.. literally to the point of retiring it, brand-new, after the first use :/) Any ideas?

The Logitech MX 518 has almost the same look but its wired. You can find them really cheap this days on ebay and its a great gaming mouse.

Logitech G300 looks kinda simillar. 

The Corsair Vengence M60 looks like a pretty decent gaming mouse, especially for FPS games. Logan does a review of it if you havent already seen it :)
