Anyone have a Nelo 540 or 550 on the east coast I could demo?

I'm thinking about buying a Nelo 540 and am curious if anyone has one I could demo briefly. I'm between Boston and New London, CT. I've been paddling an old Fenn Swordfish after 15 years in sea kayaks. I've gotten much more stable on it, but still feels a little tippy and never fits great. I don't get to paddle a ton (little kids) so figured the Nelo 540 or Epic v9 would be better choices.
