Well the Karaoke Fun Bus above was a pretty good one, by no means perfect but generally right where it mattered. That was £1500.
Probably would have made a little bit more if I had let it go the distance on eBay, but I was getting a 'quick sale'.... HA!
Then above that there's a massive jump up to the 'glorious leader' sort of things which will be at hugely inflated Bruce-tax prices (like £12000 because it has some gushing faux-modest bollocks in the ad about tracking down some super-rare accessory or getting a picture in a periodical).
There are cheaper ones too, but the difference between utter ruined sheds and the one above is pretty negligable, as they are kept buoyant by exporters.
