I've been using a Logitech MX518 for years and I love it. It's the perfect mouse - perfect size, perfect number of buttons, perfect weight, perfect clickiness, perfect styling. I wish I bought two of them when they were still available, but my experience with mice is they generally don't need to be replaced until you feel the need to upgrade.
The G502 looks to be the successor to the MX518. I'd suggest giving that a try if you like Logitech. Seems too "edgy" for me - I don't know why gaming peripherals always have to have sharp and dramatic corners and lights (which get covered up by your hand anyways).
