The original product is superb, but buying on ebay without asking the right questions first is a killer. I bought mine with full trust that "serviced" meant recently serviced. Found out service was loooong ago. Unit arrived not working, but a hospital stay prevented me from checking it out for many days after arrival, so I didn't know until too late.
My advice is simple: even tho your teeth hurt to own it, Ask if it Works before you buy it. That simple.
Teac A6010? Wonderful unit, but only if it works!
