They change hands for 1/3 of that price in working condition so it's typical ebay loser going OTT with his mouldy old shit 
The guy with videos on youtube sold his 3 months ago for about AUD$15,000. So the advert isn't that far off.
I called my brother today and asked if he wanted to have a share in this one, but he said no. So I'll not be bidding.
If it were £5k I may hazard a bid!
