Hi,

In looking at eBay, I current see quite a few different types of rubidium
frequency standards. I have seen some of these mentioned here, but no real
comparisions. The question, is what are the pros and cons of these specific
models? Which ones are best or most reliable? Which ones cannot be disciplined
by a GPS? Is there some specific ones I should never buy or others that I
should stalk, waiting for one to show up? I know that some of these may be
from the same company, but are typically listed differently. Here are some of
the ones that I currently see on eBay. Also, is it worth it to buy "lot of 5"
of "for parts or not working"? What is the likelyhood that at least one can be
made to work? Thanks.
