Don't sense any scam in the listings plmval. They read very genuine. Buy an awful lot of stuff of ebay and they read very genuine.
And in fairness have heard off guys on here that they are very hard to get hold of. Indeed I've been watching for over two years on ebay for one.
Then stone me, two in a week. I just wasn't ready for the cost reality. Had I had a drop more and on the right mad night, I might have made it £170! Have been in that position but sensible get the better of me.
That said, anyone on the site who's got one for £50 then I'd definitely go for that
