cheap-as little as possible for a functioning stand/as much as necessary. If a good one costs £80 I'll consider it, if there's a much better one for £100 I'd get that, but if I could get one for >£60 which was reliable then that would be better. In answer to how much I would be willing to pay, no more than about £100, if I can get one for less so much the better, if they cost more than that I'll have to rethink my strategy.
