The best middle ground is to pay ~$20 for H&R Block, Turbo Tax, etc. software and run through the whole program yourself first. This will take into account more than just mortgage deductions, etc. and give you a better picture as to where you'll likely end up come April given an array of different variables.

Of course a great CPA is invaluable, as is a great mechanic; but at the end of the day I'll always choose to have a good understanding on practical topics FIRST before just carelessly handing off my problem to an "expert"...nothing wrong with educating yourself on a subject that will obviously require at least some critical thinking on more than one occasion in the future as well.

What's the worst that could happen...you learn something new? lulz
