Bob, I made the same mistake as you, I popped in and out of this site and did not originally note the post by "tmilicia", so I hadn't realized that your response was to him, so my mistake too!
I did check out the "refreshed" units on the Concertone site. I had two questions. First, would the ZX85 be able to replace the ZX700 (using an adapter. I know the size of the unit is smaller) or is it only the ZX800 that can easily replace the ZX700. Secondly, you mentioned on your response that the refreshed units come with the 1-year warranty, but the site states the refreshed units get 6-months. Thanks for your help.
