I sold mine for £100 and was well made up, because I thought I'd been robbed at the £50 I paid for it, personally I think it's no more than a nice collection of photo's, the books well worth a look, but nothing over special, I'm sure John put a lot of effort into producing it, but I don't think it's worth the £200 that it's been fetching lately, just my opinion mind, I'm sure most folk are happy with it, whatever floats your boat and all.
Edited to add, the lad that bought it is on here, and he's sold it as well.
