Used steel tanks are usually safe. First, check the manufacture date. 
Remember that the tank is hydroed every 5 years (if in service). Next,
check when the next hydro is required.  Figure about $15 for the hydro
and the chance the tank will fail.  Then remove the valve after draining 
the tank and check for rust (or, gasp, water!) inside.  More than minor
spotting will require tumbling for a few bucks more. 

If the tank looks good, and is not too old (I don't know how old this is),
make him an offer.  I have purchased 15 year old steel 72's for $30 each,
and I prefer them to my new, aluminum 80's (too large). 

Buying a used aluminum tank is a more risky proposition.     

Do not buy any tank that has a protective liner inside the tank (teflon
was once a popular choice).  The liners inevitably leak and trap in moisture.
Then the tank has to be tumbled to remove the liner.

You may find a good buy on a used regulator.  I would take any used regulator
regardless of age to a dive shop for an overhaul. Depending on parts required,
this runs $25-$50 or more.

This is a good time of year to buy used equipment (at least in the colder
areas).
