In regards to the Superadio three versions have been mentioned. Is the Superadio III the one to go looking for or do the first two models stand out as better stock versions?
What about the RCA RP7887 compared to the older Superadios versions?
The second version, the Superadio II, is generally considered to be the best performing of the three (and built better than the third.) The RCA RP7887 is the same thing as a Superadio III, just with an RCA badge.
EBay usually has a steady supply of any particular model you're looking for; if you'd prefer to buy something new, the available-everywhere Eton S350DL is essentially the current equivalent of the Superadio line.
