I have ordered a Bergey XL.1 wind generator from Norman, Oklahoma to the U.K
$300 Air freight cost + whatever import duty??
I'm afraid you will have to navigate to the product page.
http://www.bergey.com/ (I don't like it when you can't paste a specific URL page from a website - seems daft to me)
I can't wait to test it out - I have tested a 500w Chinese copy in the past, and to be honest it worked well, cutting in at just 6-7 mph, I'm not sure how long it will last however, Bergey offer a 5 year warranty which is reassuring.
The Bergey does also have a pretty clever power centre (box) of electronics.
Functional Features: Low-End Boost, Slow-Mode, Electric Brake, 30A Solar Regulator, 60A Dump Load, Timed Battery Equalization, Watt Meter Display Mode, Polarity Checker
Excellent product PDF here.

Lets wait and see
