FWIW, when I bought mine early last year (US built), the rollaway package with Intensity sails was $28,650 (launching dolly, not trailer.) Brian's VX One Facebook page currently offers a North American's regatta special for the same package (including Intensity sails) at $30,995, or $2345 higher. Total pricing for the other options on my boat seem to add up pretty close to the current pricing.
Since you are the OP, also wondered if you've had a chance to sail a VX yet? Would be great to hear your thoughts!
It's a bargain. So much fun for so little investment. Cheaper sails available from Intensity that work well and a very well built, easy to sail boat with great ergonomics. The smiles to dollars ratio is excellent.
And yes, I looked closely at the K6 out in San Francisco. The VXOne has a brilliant cockpit layout and construction. The K6 may be better for the conditions in the bay.
