I highly reccomend the logitech g400. It's a remake of the MX518, a very fantastic mouse. Fits my hand perfectly, it has a few different buttons on it that you can bind to whatever. Doesn't have all that fancy lightup shit that makes mice 80$+
It performs very very well and it's only 30-40$ depending on where you get it.
EDIT: It's wired btw, but I don't like wireless, batteries is a shitload of pain, and don't have to deal with connection issues, not that I think any would ever arise.
