Pochers have become a victim of the E-bay rip off scam where the values artificially increased over time. People see a £200 item listed at £400 and assume theirs is worth £400 so they list it at £450. its a spiral upwards with each new listing. We saw it with Wingnut wings .We still see it with old Protar kits and with new MFH kits, I used to deal in vintage motorcycles spares and i watched the prices rocket on ebay. its a small world in my business so i knew what was listed and who was listing it. People would list something on ebay worth £100 for £400 then again after a week they would leave the old listing at £400 and then re list it as well at £295 and it would sell almost straight away, suddenly it was a bargain. Then cancel the £400 listing. if you followed the items like i did daily you could see exactly what was going on with the same dealers week after week.
I also follow Protar kits on the UK, easy live auction site which is open to the public but well used by dealers. the other week guy sold a collection of 15-20 protar motorcycles, many duplicate, new in boxes, i think they went for £350 ish . the very next day they were on Ebay at between £150 and £180 each . the guy even downloaded the pictures from the Auction site and used them again on ebay, he paid £350 and the ebay price would have bought him in about £2000.
What then happens is the market collapses and people are left with some very expensive items that are worth a fraction of what they paid for them and the dealers move on to another product.
