Logitech's MX518 isn't the only classic mouse which was beloved by many users, Microsoft's IntelliMouse was a standard for a long time and just like the MX518 it is coming back on the market.  The new mouse uses a custom PixArt sensor called the PAW3389PRO-MS which TechPowerUp found to be identical in performance to the more common PMW3389.  It also has shiny RGB buttocks for those that are into that sort of thing. 

There is one small problem however, it will only be released overseas so if you want one you might want to contact Microsoft!

"Behold! The one true heir to the Microsoft IntelliMouse Explorer 3.0 has arrived: the Pro IntelliMouse. It has the exact same shape as its predecessor, which is great news for many people who loved the original. It features a top optical sensor, Omron switches rated for 20 million clicks, and an RGB tail light."
