Hunter 30 T
I own a 1993 30 T.  It is a great sailing boat with good room below.  Definitely a great weekend boat for a couple and even small kids.  18 HP diseal I feel just adequate for size and weight of boat.  Need to reef tall rig when winds get stronger than 17 MPH.  Have a good survey done to check out hull and systems.  I have had blistering on my hull which are mostly cosmetic.  Boat will handle a variety of conditions as long as you handle sail area correctly as with any boat.  I think if it is in great shape go for it.
