I got a cover for my salt made at a local guy for 500. I have hear people say they have paid 900-1200. I did not use Sunbrella acrylic fabric, but the guy said I should get 5 to 7 years out of the vinyl cover i got.
Same guy quoted me 130 per cusion (not seat). I know people have said it is between 2400-4000 depending on your options for all new interior.

As far as towers, you can get your $800 monster tower or spend 3K on other models. I peronally like this one and it is right at 1000.

IIRC, everything on these is composite, except maybe the dog house base??

I would say you are looking between 5500 and 6500 for everything... just my opinion.

Someone on here once said that every boat is $12K boat whether you know it or not.... You could pay 8 for the boat and put another 6 into it or spend 16 on one that is ready to go, if you can find it...

As far as the wakes go, I love mine. I know people who ballast up their Salts and surf behind them. There are a lot of Salt owners on here who will chime in..
