Prosine Repair

I have a Prosine 2.0 that won't transfer power. Seems that this is a fairly common failure mode for these inverters....welded transfer relay. It also seems that Xantrex feels that these $1800 inverters are throw away after out of warrantee. They, nor their "service" centers that I've called do any repairs on them.

Question...does anyone here know of any place that does repairs on them ?
