Bin cages would definitely be a quick,cheap,and simple option!Of course,once you make them expensive they aren't a cheap option anymore which defeats the purpose of bin cages in the first place
However,there are some bins out there which could be connected together directly to form a cage that has more floor space than even a Detolf for a much better price in terms of the actual floor space in comparison.There are definitely a lot of benefits that bin cages have which others don't,and while they're not the nicest to look at they get the job done and that's what matters.
