Hi Rob,
I'm looking at a Scanstrut 8' mast with a self-leveling mount. It through-bolts to the deck and has two support struts, one mounted on the deck and the other on the pushpit.
The cushions came in around $4,500. It wasn't the cheapest of the options I considered, but going with a local company meant they could visit the boat and pattern everything directly. I also had the option to re-use my existing foam (which would have lowered the price) but mine is too far gone to be salvageable.
