My Taxes!?!?

OK, so last year was the first time I really had to try to do taxes, with a full time job being paid 100% over the table, without tips. I just went through the motions of filing online, and I think I even did it while watching a movie or something and only half concentrated. Basically, I just did a half ass job, didn't think about my deductions and walked away having to pay an additional 36 bucks, plus the fee for filing online!!!

So, this time around I'm debating whether or not to go to a tax guy to help me this year. I'm not so sure I want to risk doing something wrong and missing out on what could be a few hundred, if not thousand bucks.

Any thoughts?
