That thing really isn't in all that bad shape, peel the stickers off, clean it (especially that dial face
) and hit it with some wood polish, it'd prolly look about as good as new. Hell, it even still has the original schematic and a fairly clean chassis. That said, it's definitely not worth $150 to me, but it's not an absolutely absurd price for that. Some of his other prices are kinda bordering on absurd, but simple laws of economics will take care of that and we'll see those relisted for less, probably a couple of times before they finally sell.
Edit: I also just noticed there aren't reserves on that stuff, so it's likely it'll go cheaper than the BIN. If it was closer I might even go for that Grundig console he has starting for $200...
