I need a new mouse please!

Hi everyone, I need a new mouse.
I have an ASUS G73, and I play a few FPS games but most of the time I'll use it for web browsing and such.
I'd like it to be wired, ergonomic, maybe have some programmable buttons, and functional on multiple surfaces (like my bed).
My budget is anywhere under $100 USD.
Thank you for any suggestions!!
