There are lots of used tuners on the market, but in my opinion most are not worth over $100. Clearly there are exceptions.My experience is that the old Philips AH673 is a good tuner, once it has been refurbished and aligned. But the cost of a good refurb is several hundred dollars. A Magnum Dynalab MD90 tube is close, but it depends on what each tuner sells for. Check out my comments on Canuck Audio Mart tuner forum.
