I'm not going to weigh in on the ethical aspects because I have 2 sanke's that were legally purchased from our good friend oneal66 at Rahr and Sons Brewing and a third from a scrap yard which is technically illegal. I love them all though (feelings), and it's great to give a damaged or otherwise useless keg a new life.
Another idea for larger, safer (than glass) fermentors is using the 15 gallon plastic vessels that LHBSs' dispense their LME from. I picked one up from a local shop for $5 and will repurpose it for my next batch. You can't beat the price since they would probably just throw it away otherwise.
