Have a look at the comparison table of various products at
Wind Generator Comparisons - Fourwinds Enterprises.
I have an AirX which is noisy but seems to produce well at higher windspeeds. I was impressed with the quietness of the Rutland 913 but it's output appears to be rather low.
I currently also have one Solara 225M solar panel with which I'm happy with, planning to install a second.
