My qualifications would be wireless, laser light, scroll wheel, things most mice today should have. Also, I'd want it to use 2 AA batteries. That way they last a long time, and if you use rechargeable's, some lower end chargers will not charge just one battery. Lastly I would not worry a lick about ergonomics. Your hand will get used to just about anything in a day or so.
This the one I use Dell WM527 meets your spec's but uses 2 AAA batteries, only had to change them once after 9 months. I use it with my XPS 8930, my Dell Inspiron laptop by way of Bluetooth
