If you're not big on the gamer look of the G502, which I'm not the biggest fan of either. You should check out the Logitech G303 which has a much more minimalist design and doesn't scream "I'M A GAMER".
I'd also recommend just grabbing a new Deathadder since they seem to come out with new revisions each year. Although I've never actually used one myself as I tend to stick with Logitech mice. Either way, it's always a gamble getting a new mouse, that's for sure.
