The last poster is dead on.
I just had Sail Trailers build me a trailer for my 260 about two months ago, and I couldn't be happier. They're a couple of sailors themselves and they started out a few years back building them for friends.
Also, if you're only moving occasionally, they will rent you one of theirs. And they're in Georgia, so you won't even need to go far to get it.
My experience: they started my trailer on a Thursday and it was delivered to my driveway in PA the following Wednesday about 11PM.
Actually it could have been done by Monday but a) they had some trouble getting the first coat of paint to dry and b) they knocked off early on Friday afternoon because the wind was up and they wanted to go for a sail.
Tongue extension, nylon winch strap, ladder, spare tire, double axle, 7000 lb GVW, 15 inch tires and built specifically for my boat.
And really nice guys to boot.
