$500-600 Used Tuner
Like to get the current feelings of some of you here who know their tuners. I have a late-70's tuner that actually functions fairly well, but I find myself listening to FM jazz stations more and more and would like to take a step up without breaking the proverbial bank. Suggestions on the best value for a tuner around $500-600 USED.
