FYI
Noticed today that the warehouse is selling 28litre Aliminium cray pots with a burner and lifting tray thing... Its on special from $100 down to $60 and is pretty much everything you need to get BIAB'ing apart from a bag and some grain.. Youd be able to get away with about 20 litre batches with this..
Kettles generally the most expensive part and this is cheap cheap cheap!
