My dad was in a neighbor's barn the other day and saw a few used hive boxes stacked around. He wasn't positive, but it sounded like maybe there were around four or five large hive boxes total. He peeked in one of them and it was full of frames. The boxes were bright white and looked more or less brand new. The neighbor was talking about how he might want to get rid of them (wasn't sure--just thinking about it), and my dad wants to make an offer for them on my behalf. No idea what the going rate is for used equipment in good shape. What would you offer?
