I sold a few vintage Tizio lamps, with the old style halogen, for €130 per piece last year. Took a few weeks to sell them. In all fairness, they were missing bits like the glass panel and one had two paint splatters on the head.

Nice lights, but not the easiest to move, a bit fragile and not very power efficient. The LED ones don't power on when you apply power to them which is a strange choice and makes it difficult to integrate with wall switches.
