I'm wondering if there is some other criteria besides UHF (I presume in the 
430-440 MHz band) and 100-200 watts out and linear operation? Because there 
are many amps that meet those criteria.

If you want brand new, you can find them from Mirage (not my first choice, 
our repeater club and some of its members have had bad luck with 
workmanship and keeping them operating), TE Systems (I've heard plenty of 
positive feedback from folks with the exception of dealing with the company 
for repairs), and some others.

In the used market, I have had excellent results with RF Concepts bricks on 
144, 222, and 432. If you find one on the used market, it will probably be 
quite satisfactory for you (I don't believe they ever made a unit that 
produced more than 100 watts out). Teletec amps seem to be quite rare on 
the used market, but that's probably because most folks that have them 
don't want to let go of them.
