I purchased from Overton's the Quick Anchor Mini Genius Free-Fall, cost $849, then you have to buy the anchor rode as well, you cant use just any rope/chain. With all materiel included, I spent about $1,100. I imagine it increases the boat's value...man is it nice to raise and lower from the helm! I bought a new plow-style anchor, the wieghting make them more user friendly on a windlass as opposed to the danforth or fluke style. In retrospect, installing the windlass was challenging only in routing the 6 gauge wires to the bow, I would be happy to provide you a diagram, so you can learn from my mistakes.
I went to Lke Meade two weekends ago, used the windlass many times, it was wonderful.
