HSA vs. Traditional Health Insurance Plans

First off, sorry for the novel, but I couldn't see how to shorten it before posting as I want to provide enough information to get some solid feedback from you all.

My company is going through open enrollment now, and I am seeking advice from you all about what you would do if you were in my situation.

My situation - 29 years old, married, and have a 2 month old son, all of whom will be covered under my plan. Wife does not work and will be part time if she does ever go back to work, so no penalty from the President there. I work for a Fortune 500 company with insurance through Cigna.

I've always went with the traditional plan in the past and been relatively satisfied with coverage. However, in response to Obamacare, my company has jacked up the rates and now has me questioning which plan I should enroll in. It's going to cost me $4900 in payroll contributions under the traditional plan, but only $2250 under the HSA option. My employer also contributes $750 each year to the HSA plan, but it has a $3K deductible to meet before the plan pays benefits which I believe are then paid out at 80/20 by them.

I am in good health and go to the doctor maybe 2 times per year, and my wife is also in pretty good health though she has issues come up slightly more frequently. Everything with my kid seems great so far - he's happy and healthy through 2 months of his short life. We do not plan on having another child until 2015 at the very earliest, which was the greatest cost for insurance in 2013.

Would you continue with the traditional plan or enroll in the HSA if you were in my shoes? I guess I'm also looking for pros and cons to each as information from my employer and Cigna seem sort of ambiguous on the HSA option.

Thanks in advance.
