I thought that i would be nice and let my fellow builders know about a Cintiq 21UX on ebay as we speak for about $530 inc p&p. The caveat is that the glass protector panel is broken but the thing apparently works no issues. Anyone on here should be able to find themselves a glazier that can match up a piece to fit and have themselves a dead cheap Cintiq.
here's the currently live link but i wouldn't expect to see it around for too long: http://m.ebay.co.uk/itm/261447313578
If import charges to the UK weren't so high I would snap this right up.
p.s. I have no connection to this sale whatsoever, just thought someone might be interested.
