Hah! I knew I had a link somewhere!
You've still got a couple of options:
1) Nations Auto Electric. These guys seem to be into the High Output stuff. I haven't heard enough reports from the field on them to form a cogent opinion - anyone who decides to call them, I'd appreciate a field report for reference.
2) San Jose Generator. Yep - I'm pimping here! He's the guy I've used for years, does good work, and I talked him into doing mail-order a couple of years back. He won't do winds as high as Nations or Mean Green (yet...) but he does do damned good work and his prices are fair. If you call Rod (he does keep banker's hours...) you'll be talking to the guy doing the building and testing, or supervising the guy (since he's only got one employee.) You can get his information by clicking the link in my sig, scrolling down to "San Jose Generator," and clicking there. He may have changed prices - I do try to check with him at intervals, but he's been pretty stable so far. A few guys here have ordered from him, and seem to have been happy with the results (you can probably find out for yourself by searching either for <SJG> or <San Jose Generator>. Ignore posts from me - they're probably more pimping.)
