What items do you rarely ever see offered for sale


What items do you rarely ever see offered for sale? The stuffs that people buy and keep for long long time, regardless of financial or WAF difficulties. I'll cast my first vote: I have never seen a complete properly built and stained Edgar Horn Titans system offered for sale, maybe because there are very few made?

Vintage Janszen Electrostats. Several versions of the 130's. My Dad has them mounted in his vintage KLH model-1 bass cabinets.. Really nice and very much ahead of their time! Any one ever heard them or have/had them??
