Advertisement I think that once you want to scale larger, the bins are really the better options and have lids like you were talking about. The buckets are nice for portability and space saving. If you want multiple smaller roach colonies(to be able to move them around easily or having different species for example) I think the buckets are a great solution. In my case it wasn't necessarily the cheapest because I had to insulate and heat the bucket separately from the room but I do not wan to keep my garage hot . In summer time the heating mat will probably be off more often than on. It is the most convenient for me though.
