I'm an AT enthusiast and am considering investing in a pair of W5000s. I own a pristine set of Audio Technica W1000s complete with packaging and a recent receipt from Japan that I'd sell for £160.00 plus postage if I go ahead with the deal for the W5000s.
These are magnificent 'phones that I'd be happy to keep were I not so keen on getting their big brothers. See this review...

Contact me through trust if you're interested.
Oooh. Depending on how much I could flog my A900s for I'd be dead tempted by those!
