Perhaps, but that one is in Pittsburgh, you are local, can pick up, and have cash in hand with no listing, final value, or paypal fees. Take any high sale price on Fleabay and take about 20% off, then you have what the seller is actually getting. So take $325, and reduce it by at least 20%, so offer him between $150 and $260 and see what happens.
There is a local guy who has a Loewe Opta Hellas model, it's one of the better ones with around 11 or 12 tubes, and supposedly stereo. The guy had it on craigslist offering for best offer, but that was not what he really wanted, he wanted about $625 for it because he supposedly saw a restored one for sale for $1250. He also said that if he couldn't get that then he would rather keep it (yah right! If you wanted to keep it you would not be posting it on C.L) So I humbly suggested he try contacting whoever the person was with the $1250 one and see if they might be interested in buying another, since it was highly unlikely that he could get anywhere near that for his set around here, no reply as usual.
Try as I may I could not find a single example of his set for sale for anywhere near that much, it was from around 1959-60. I saw a very old ad on Canuck Audio Mart with one for sale for $275, I do not know whether it sold or no but I would guess not. Canuck Audio mart is one of those boutique websites where every other goof thinks his piece of garage sale fodder is rare and valuable audiophool gear, so if that set wasn't priced for $1250 on there it wouldn't be anywhere. The guy changed his listing, he is now asking $500, he will not get it, guaranteed. There is an air base in the area and loads of retired servicemen who guess what? They did a tour of duty at Laar and Baden in Germany during the 1950s and 60s, German sets are not in short supply.
