I am honestly not trying to offend you, I'm just being logical that you have no feedback on this forum.
When you buy or sell something you add feedback by clicking on the users feedback score and then clicking the 'submit feedback score'.
I'm happy to have a member vouch for you of course
As for the value, no offence taken

- to me £150 is a lot of money, I appreciate to others that might be small money - at the moment I'm not working hence 'rationalising' my collection, hence to me it is a lot of money!
If you would prefer I would be happy to list on eBay and forward you a link, but would need to add a little to cover the fees (around 15%). This is still cheaper than I planned to list on eBay if it didn't sell here
