Re: should i use, used beekeepin equiptment?
Welcome to Beesource!
Reusing hive equipment with an "unknown" history is a risky idea. But beekeepers, big and small, do successfully buy/reuse some else's equipment. The trick is to do so only if you are confident that the equipment is not infected.
I suggest that you talk more to the potential donor. Ask him about his experiences and practices. Bring up the subject of possible contamination. See what he says. If you don't like what you hear, then graciously decline his offer.
This is a judgement call, and you will hear lots of opinions about this. But few things in life are certain, and every day you are faced with decisions [unrelated to beekeeping] that have an element of risk. This is no different.
