Without getting into the debate on Part 90 vs 95 figured I'd list some basic Repeaters for UHF that would be good base units if your shopping for new.

I left the KG1000 off the list as its not a repeater. Its a mobile radio. The goal was to give folks out of the box repeaters.
If we got into radios to make repeaters there would be hundreds but they all require 2 radios, controllers, cables and programming.
