I have a bad unit that'd I like to have checked & repaired. Has anyone had success have one fixed? I found a company nearby (150mi) that I am willing to try, that is unless there is a better source or some bad references.

The website is: http://www.foreignecurepair.com/rnr.htm and this is part of their link.
