Lowe's has food safe/BPA free 5 gal buckets (for $4) - anyone used these as a secondary? Seems like they would work perfectly and would allow little headspace like a carboy. All I need to buy is a lid & an airlock from my LHBS. Esp. good for my setup as my ferm freezer (which is large enough for two buckets) has a shelf that doesn't allow me to use my 6.5gal bucket with the airlock.
I have a white lowes 5 gallon that has a 1 on the bottom and it's made by Encore plastics. I'm 99% sure it's food grade. I use it for a secondardy and bottling bucket because it's not quite big enough for a fermenter.
