And even long after the end of life of a product Symmetricom was really helpful - I have an NTS100
(not the i version) that I got on eBay and they dug up a manual for me and were able to find
somebody who could answer questions.  The level of service we very impressive for a 10+ year old
product, it's unusual and pleasing to see a company stand behind a product that old that they got as
part of a merger. They are on my list of good vendors when for when I spend company $.
