Welcome Miranda!
My cousin has a T-30, 1976, with a side galley. Nice boat, very responsive.
I think that you'll find the T-37 is a great boat for the money and well pedigreed. What are your plans for a larger boat? The T-37 can fill most requirements and is well suited for week long (or longer) cruises. If extended cruising is in your plans, the T-37 will need some modifications, but certainly a great platform to start with. She's not going to win many races wire to wire, but she's no slug and if you like fingertip steering, it's hard not to like (love?) a T-37
