I'm looking for a decent wireless keyboard & mouse combo.
Ideally, they'd have:
Mechanical, back-lit keys (less important)
A large mouse with subtle grooves to grip it with.
Keyboard should be a decent size with rubber underneath to grip a desk.

Does it even exist or will I have to settle on one or two points?

Any model suggestions welcome, but would like to avoid Logitech's unifying receivers as I have had issues in the past
