Wind Generator, which one???

Anyone own and use a wind generator that is larger than 800watts? I would like to know how you like or dislike its performance. Looking for issues like how much noise does it make when its spinning, does it auto gyrate on spin down, does it really help provide power for your system, how high is your tower, is there problems with icing in the winter and vibration on start up, what was the total cost of the installed system, are you happy with it or do you wish you would have gotten a larger unit? I am looking to install a system around 1kW to 3kW and want to here about any or issues good and bad before I spend the money.
