I don't have a mouse recommendation, but if you're interested in repairing your old mice:
Did the encoder fail(doesn't scroll right), the switch fail(click problems), or the wheel physically break? If you aren't afraid of a soldering iron those first two issues are pretty easy fixes.
Assuming it uses the same encoder as the Spawn, it would be ALPS EC10E1220501
Switches would be D2F-01 or D2F-01F, depending on if you prefer heaver or lighter click force.
