Check out this joker....$6700.00 for a used Accentra insert, and that is the minimum bid! Looks lke he got hosed on the purchase and install. Still can't figure out why he says "it does not work for our residence" when he used it once? Why doesn't it work? http://cgi.ebay.com/Harman-Accentra...emQQptZLH_DefaultDomain_0?hash=item1c108848f1 Oh yeah, there a listing for another Accentra insert for $3000.00. Hope Mr. $6700.00 is not holding his breath.
