I've had a Good freefall windlass for 2 seasons now. I replaced (upgraded with a tradein allowance) to a rope/chain as well. The freefall option is really nice, because the rope is not engaged in the windlass, letting it pay out as you set your scope, then you hit the switch and lock it.
They usually provide you with 10' of chain, but you can negotiate this a little. I got 15' of chain and the standard 200' of rope, which has been more than adequate for my 33' Sundancer. If you have existing wiring, try that first with your new one. You may be able to use it. Good also has decent customer support.
