It seems replies leaned in the "probably OK for the right price," and "this is common in the north east" direction. I bought the boat, and all is well.
It's an Alchemy S, from Mountainman Outdoors, in NY. I was going to get on here and post that they had another one at a good price ($779, and $99 for Forward Air shipping), but, they sold the second one shortly after I made my purchase.
They were good to work with. I had noticed some other kayaks at good prices on their site. Not sure if they're still there, but, it's a good place to check, if you must buy long distance.
The only thing "wrong" with the boat was that the bungees were slack. I had to take a whopping 18 inches out of the front deck bungees, to get them right. I've seen Confluence bungees that were semi-loose from the start, so, the looseness of these may not be entirely due to age.
