Is anyone on a High Deductible Health Plan? My one coworker swears it's the way to go, saying that even if you pay all deductibles it ends up being the same cost as the regular plan. Therefore, you can only save money.
I haven't crunched all the numbers yet but am not sure what to do.  With a toddler (almost 16 months) I hesitate as you just never know.  Plus, we may get pregnant next year and with all those doctor appointments I don't want to pay out the wazoo!

I will add that one thing that I like is that the HSA continues to grow and grow. So if you have a few years where you use hardly any of the money, but are able to contribute quite a bit to it, you can get into the position where the balance of the HSA equals your total max-out-of-pocket for the family. Meaning, if everything bad in the world happened and you'd be liable for $10K of medical expenses as a family, and you had $10K in the HSA, you don't need to sweat anything. You got it covered. Then the following year, you can switch back to something more "safe" or "known".
My DH started the HDHP with HSA when he was single and just kept contributing the max to it, but took out very little. Now we have $20K in there, so it would take 2 consecutive years of us not contributing any more to it AND having to meet the full out of pocket as a family before we exhausted the money.
I like to think of it as a separate medical emergency fund for that purpose.
Quick number crunch for us:
Low deductible: $300 per month (3,600 per year) in premiums, plus $1000 deductible, co pays and it was a 70/30 after the deductible.
High deductible: $90 per months ($1,080 per year) in premiums, plus $4,000 in deductible, co pays and it was 90/10 after the deductible. PLUS our employer contributed $2000 to our HSA (every year, and it carries over)
So we saved 2520 in premiums, +2K from the company that was more than the 4K deductible and we end up with better coverage after the deductible. If you don't spend 4K in services for the year, you get to bank that money.
just and FYI, one of the PP mentioned that pregnancy should be covered, it IS NOT in all plans. I had to pay out the 4K for my pregnancy in 2011 before the insurance kicked in, so just ask a lot of questions before you sign on the dotted line!
I switched to one this year. Mine is 3,600, of which my employer pays 2K. The yearly premium I pay is less than 2K. It has no copays and once you meet the 3,600 (really only 1,600 I have to pay) it kicks into the normal ppo I had before. So it was a no brainer, although I am tracking everything spent this year so we can compare when it comes time to rejoin. There are two things you have to consider: are you a highly compensated employee whose employer takes the premium out pretax and do you have the money in the bank to cover upfront costs that may be associated with a higher out of pocket expenses? If you are highly compensated even though it appears you are paying more the amount you may be saving in taxes could make the more expensive plan a better one it all depends on your tax bracket. I ran every number overall and figured out worse case scenario say I got really sick the cheap plan would end up costing less than 1k more than the more expensive plan but if everything went as normal I would be out a couple 1,000 on the more expensive plan but it is insurance so I would not have been hit with a large bill at any one time because it would be covered in copays etc.. but I may have been paying for something I rarely use especially with well visits covered. It is a risk but as long as you have money in the bank to cover out of pocket expenses I think it is the way to go at least at my company.
