Cons: maintence every 6 months
It is a well designed machine and has what I found to be good instructions in the assembly manual. I did most of the install myself and had the dealer spend 2 days assisting me with the final wiring and standing the tower. The kit was about 47,000 USD and about another 10,000 USD for the concrete, rebar, wiring, drill rig to bore the holes for the foundation, crane to stand the tower, and the dealers labor. I spent a few weeks of my free time assembling the tower and building the rebar cages. My tower is the 120 foot angle iron style all of the holes are pre drilled in the 1/2in thick galvanized steel lags and the lighter brace pieces. Every hole was perfectly placed I did not have to oval out or re-drill a single hole. As long as I had every thing lined up straight the holes lined up. The turbine is relatively quiet, I can only hear it when I am outside near the unit. If I walk aound behind the house it is not audible. It is definately a project that I would do again if the situation arose.
