Here is my short list of recommended home machines:
ReVox A 77 Mk III and Mk IV
ReVox B 77
Teac A series (X series are better to avoid, the DC capstan motors and motor switches less robust)
Pioneer RT 707
Pioneer RT 1020 and relatives are superb machines, I recommend those a great deal to anyone.
3 motor/3 head better Sony machines if in top condition only
Crown 700 and 800 series
Otari is mainly geared to 1/2 track Stereo recording. The MX 5050 B II does play back 1/4 track tapes and can be used on slow speeds. But more professional/broadcast oriented so consider that. If you want a 1/2 track machine, I recommend them highly. I assume being home that you want 1/4 track and slow speeds a la 3 3/4 IPS/ 7 1/2 IPS. I do not recommend Akais in the USA due to parts supplies very unobtainable, especially non relappable, unobtainable heads, many of which do not meet spec. In Europe, Akais are more recommendable due to the Akai agents having kept parts stock in good supply. Rank represented Akai in most of Europe and did the best job of being Akai agents. In the USA, Akai didn't have anything as good in the USA behind them. Regardless, I do not recommend the GX 77 at all. Very weak motors.
