I bought my Hobie in Newport, NH from Alden of Sunapee... no tax and I got a life jacket thrown in. There is a good dealer in Rowley, MA but you will have to pay sales tax. Alden of Sunapee had a DEMO Revo Fish available when I stopped in to buy turbo fins in October. The best site to learn more and read fishing yak review is:
New England Kayak Fishing • Index page
Great guys and a lot of very good fisherman that use sluggos, and live eels
