David,
Not really qualified to give you a value I’m afraid but I bought a fixed keel SS26 a couple of months ago, built in 1984 and I paid around £14,000 for it, I don’t know if that was a good price or not compared to other boats but I am more than happy with the purchase, as you say the Super Seal ticks all the boxes.
Mine has been well cared for and is in good condition for a boat of her age. She came with a basic inventory and some things have been modernised/updated, new-ish mast, standing rigging and sails (2004) but as with most boats there are still plenty of things I could spend money on.
I suppose the consideration is how much time and money you think you’ll spend on her? You should compare this with other boats as sometimes a more expensive boat in better condition can prove to be better value in the long run.
Hope this helps
