Have you considered a 232 Gulfstream? They were produced up until a year ago or so and seem to be much more common/desirable than the 265 Express, as well as the 268/270 Islander is. They're also a bigger, heavier and longer boat than the 228 Seafarer, along with having a considerably larger cabin.
My neighbor has a 2005 GW 270 Islander but we're out here in the Seattle area and nowhere near eastern NC. I've been on his boat a few times, the cabin seems like it takes up more than half the boat and I honestly like the layout of a 2006 and newer 232 Gulfstream better. I can stand up just fine inside of his cabin of which I'm 6'2" tall, but as mentioned, it seems like the cabin takes up a good deal of space that could be used for deck space, fishing or other things. Or at least I don't think I'd ever need a cabin of that size, and I don't believe he's ever overnighted on the boat before either. As mentioned before, there's about 12 boats to pick from between the 265 Express and the 268/270 Islander that you mentioned you were interested in, whereas the 232 Gulfstream has 26 to consider, at least on Boat Trader that is.
