""There are a few reasonable quality Chinese import PMAs at very reasonable price and if I was going to buy something I would go that route rather than something based on a car alternator""
I've read posts from you along those lines several times and just have to ask which PMA's you are talking about? Please know I won't take what you say as any sort of endorsement, guarantee or the like but just an opinion. I have wondered if this one from WindBlue might be OK.

I have tested a nice alternator from Ginlong technology or something that was well made and seemed like a nice choice for about 8ft. They have others intended for grid tie.
I don't know of the source, one off cost would be prohibitive, but in reasonable quantity the price was very reasonable. This was a test sample so I can't comment on general availability.
