I bought a Hornet wind generator on EBAY for about half the price of a KISS, even after factoring in my cost of wiring, mounting pole, paint, and straps. It looks like a homebuilt (read ugly) but it is whisper quiet until it hits its resonant frequency (at about 33 knots). Even then its doesn't get loud just a vibration. Performance seems to be inline with other wind gens. (ie the pits at 0 to 9 knots, then quickly ramps up.) here's their website:
Some times they sell new units on ebay at a discount.
My setup - 4 Kyocera 40 watt panels and two flexible 32 watt panel for a total of 224 watt of solar. A Balmar 110 amp alternator on the diesel, a small gas powered portable genset and the Hornet 1000, six 6-volt house bank - 540 amp-hrs. Flexible, multisourced power.
