Appreciate the counter points. I wasn't suggesting the R100 was not a good unit, it was good for what it was built for, which was not to be a 100% duty cycle heavy duty repeater. We sold alot of them when I worked for M, and they generally were great. I did see some melted down because the customer needed a MSR2000 or MSF but didn't want to spend the money. I would hate to see someone buy one that may essentially be salvage, and may not be working....but buying one from a seller that can test, and would take it back if it wasn't what he said it was, would be better. Especially if you are are just-getting-started radio guy. I would disagree a bit on the Radius and Maxtrac....I have seen many a small repeater made from them, and they are a reliable, well made mobile. I have some that are 20+ years old and work just like new. I do understand that everyone's experience will vary, we each like what we like.
