Consensus seems to be "buy old-school", which is fine with me - next question of course is whether you've got any great suggestions on where to actually do that buying, preferably online? The local shops are mostly factory brand affiliated and carry only new stock from those brands - even to the point where trying to get hold of internal parts for my very common Mavic freehub was a chore far beyond my expectations. Should I just find a refurb seller on eBay and stock up?
