You shouldn't scare her

Some Nak's are a nightmare but most of them are very easy to service. Also cheap. But it must be said that it has to be a non-butchered one. A dragon ... Everyone has heard of the name but really, the BX-300 is a wonderful three head deck. A three head deck is what you husband wants and, the BX-300 is an outstanding deck for a normal price, and probably the most sold one as it was a huge hit. Over the decades it turned out that those plastic mechanisms with their worm wheels are actually very good as, most of them still survive today. And that makes any cheap Nak of interest. But be sure to have it properly serviced, which is under a 100 euros (fresh capacitors, cleaned motors, fresh brushes, new belts if any, new pinch roller, idler tyre, etc) I still have all my ancient cassettes from when I was young. I use the BX-300, bought long ago and fully serviced it. But I also have a BX2 in the shop (not a three head) for playing cassettes. One of the cheapest Nak's there was ... But then, even the cheapest nak was an outstanding deck. The RX-202 is an autoreverse deck, more expensive, a good one but do you really need it ? You don't need a nakamichi specialist, just a good tech. But at least give your husband a three head deck. He will love you for that.
