Is Turrican 2 CDTV Worth £186 in Very Good Condition or do you think this is overpriced?
That particular seller is very famous in Germany for asking ridiculious prices. If you check ebay Germany regularly, you'll see plenty of his "rare", "shrinkwrapped", "mint condition" titles for astronomical prices.
Also, he once sold a copy of Giana sisters, where it later turned out that he had bought it via an Amiga forum without packaging and then resold it on ebay with selfmade packaging claiming it was completely original. The whole story is somewhere on EAB.
Stay clear.
