If you're looking at a professional tax preparer purely for the time/effort savings, it might help to remember that a big chunk of the time spent doing your own taxes is simply gathering up and organizing all the relevant information, and you still have to do all that with professional tax prep.
I had an accountant do my taxes for a while because my condo went from owner-occupied to rental and I thought it would make doing my own taxes too complicated. Turns out that TurboTax makes it plenty straightforward, and now I have a much clearer picture of my tax situation, having done my taxes myself.
