those 10k and 15k deductibles seem a little too steep for me
The thing you might not realize is, most standard plans start covering way earlier, but once the initial deductible has been paid, they are like 20% co-pay to infinity. So say one of your insured family members gets way sick, say $100,000 cancer sick. In my HSA plan, I'm out the first $10k, then that's it, I'm covered for the other $90k (per year). In a standard plan, your deductible might be $1000 up-front, then 20% co-pay beyond that. So you're out $1000 + 20% of $99,000 = $20,800.
Of course that's an extreme example, but IMO that's what insurance should be for; the extremes. There's a major philosophical difference between "insurance" and a "health care plan", I personally prefer "insurance" to cover only the major unexpected stuff, and to pay routine stuff out of pocket. Do you insure your car for routine maintenance like oil changes and new tires?
Then this gets to my major problem with the medical industry today: since most people are paying for these high-cost, high-coverage plans, they have no qualms about using them. Routinely. Every takes an "abundance of caution" approach (patients, doctors, nurses) and countless money is wasted each year on pointless tests, medications, and procedures. When it's "use it or lose it" like a standard plan (if I'm paying $800 a month, you bet your ass I'm going to be using it) then you have no incentive to limit your consumption of medical stuff. So people do things like go to the dentist 4 times a year, get new glasses every year at $500 a pop for prescription + lenses, etc. Which is all pointless, except it keeps the dentists and optometrists in business. I'm not saying that I don't understand or appreciate a preventative approach to medicine; however, I believe that costs have spiraled way out of proportion to the benefit provided.
Getting back to the practical issues... with the standard plan, you're paying like $500 a month (conservatively -- probably more like $700 or $800 a month) instead of $200 a month, your whole life, whether anybody gets sick or not. Take that $3600 extra per year, put it into the HSA, and in 3 years of non-sickness, you've got your $10k covered and earning interest (HSA's can be invested like IRA's, and if you've got money in the account when you retire, it can be rolled over into an IRA). (BTW the HSA contributions and withdrawals are also income tax free, so you're effectively saving 25% or more on health care costs that you pay for out of the HSA savings.)
As another note, IIRC, I think I could have gone with a $5k deductible and it would have been in the $280 a month range. Again, this is coverage for 2 adults only. Pregnancy is not covered under individual health care plans in Texas.
