SteelSeries Rival, I had for a while. It's pretty awesome, and pretty cheap. Although I've given it to my brother and I got myself a Logitech G400S. Optical mice are my forte;I really don't like laser. They just feel off to me. I recommend the SteelSeries Rival or the Logitech G400s. They're comfortable, precise, and relatively cheap.
Kind of like my really old MX518, that's what they are basically. Nothing too fancy, but that's what I like.
