Michael, thanks for the info mate. Don't worry, I won't crowd you on ebay!
Andy, that's a kind offer which I appreciate. There's too much to sort in time for 10 August and no immediate hurry after that, so I shall start haunting ebay for now, I guess. Thanks for offering (once again) to bail me out.
Cheers guys.
If anyone is selling bits I've listed, don't be shy!
