Mike, yours is a very good comment, Moto / MA/COM. Probably the best approach would be to compare specifications, and take a good look at each product for serviceablilty. Don't forget EF Johnson - I have 10 or 15 of their VX series, and 5 or 6 M3, and a handful of Kenwood TKR820's and such that I use in my own LTR trunking systems.
By large and far, modern equipment has been very trouble free. In my real life I maintain 78 MA/COM M3, 800 Mhz Edacs repeaters, 4 Sites, 19 channels per site, simulcast, with a couple of NPSPAC channels for interoperability. I do know how the Maytag man feels. Best luck on your selection of repeater. More important....location, enviroment, antenna, transmission line, grounding, shelter, accessability, and such. Steve NU5D
