A lot of the older Sony stuff commands high prices, even the lower end models. I recently saw a Sony ICF-38 (a very good AM-FM portable, almost as good as a Superadio), which was discontinued two years ago, going for $199 -- new in the box. I got mine about 5 years ago for $24.
The Sony EX5MK2, probably one of the best MW portables made, was discontinued a year and a half ago. They went for $150 new. Now they've sometimes more than doubled in price.
On one of the ham forums there are some threads complaining about used receiver prices... R8's, IC-71's, etc. commanding super high prices, used.
I think I saw an advertisement for the Sony CRF V21 a long time ago. Looked like a very complex radio, especially with the printer. It seems one would have an issue finding paper for the printer nowadays, though.
