I wouldn't judge the things so hard. The Beovox 1702 is a wonderful sounding speaker and it's size is perfect for the office or similar. I have a pair in the workshop that I use for soak testing. Try them out against a pair of, say, CX50 and the 1702's will win, leaving the CX50 sounding sterile and cold.
The Beomaster 1001 may not be rare or specifically sought after but visual condition is everything and if it's good and good photos are taken I'm sure that it will go well on Ebay. Make sure to accept overseas bidders and be ready to pack it carefully.
The Beocord 2200 is a wonderful machine, superbly build, easy to use and hardly ever failing but being a mere cassettedeck, it may not appeal to many people. Cassettetapes haven't had the same revival as vinyl records - at least not yet but it's still one of the better quality decks from that time.
Any way you put in, these are all HiFi design-pieces from the hands of Jacob Jensen and the presence of the original boxes and manuals will double the income, take it from a B&O collector.
