Steve,
$314 is a great price on the autoformer. Also, somebody may really get a deal on the one on EBAY.
After using our coach last week, I can not say enough good about the autoformer. We have always had problems with breakers tripping because of low voltage at the Shore Power post. We did not have any breakers tripping even with the A/C and W/D going at the same time with the TV and other smaller loads going as well.
Here's another source of info at the Hughes Autoformer WEBsite if anyone is interested:
