Asmartman,
I have a call into our warranty company and also to G&K. I know that G&K had ordered a few of these for some warranty claims. Not sure what happened to the old units, but I've asked the warranty company to send me (or you if you give me your address) the next unit that comes available through a claim. I'm also calling my parts supplier to see if there is a way they can send a bad unit to me, but that's from a Mercedes dealership and I think they might be more reluctant to do that.
