We had ins. the whole time I was young. We had a few things that I'm sure it really helped with (I was really too young to remember it all). After my dad started his own business, the premiums were going to be over $1200/MONTH for our family (2 adults and 5 children). (At the meeting my parents went to, the company rep told them that they were paying for everyone else's drug rehab, lung cancer, and other crazy stuff


They decided at $15,000 year, that would pay for a LOT of medical bills, so they dropped it. For some reason, we got to keep our eye ins, though - it was a dif. plan altogether.
We went to the Chiro regularly (which would not have been covered by ins at all, anyway), and researched how to stay well. Did we do without sometimes? Yes...I have acute chronic athsma - I couldn't afford Advair, Xopenex or Z-Pac for my lung infections, so I used Albuterol only and dealt with the shaking, and generic abx.
We weren't accident free, either. My brother had severe pneumonia once, and dad made a little too much to qualify for Charity care, but the hospital settled with us. Dad ground his thumb to the bone with a sander, and paid $450 to see the specialist for 10 min. - only to learn not to use peroxide, but rather baby shampoo.
I was in a bad car accident in July 2007 - totaled my car and severely damaged my neck/spine. My car insurance paid for every dime - including MRI's (Total of $8,000). In July 2008, I got SEVERE food poisoning (from Panera - still can't eat there

) EVERY PENNY (almost $6,000) was taken care of because I was old enough to be responsible for my own bills, and didn't have the income at that time.
All of the above cost us less than $10,000 in the 10 years that we didn't have ins.
Fast forward to now - my husband has group ins. Since we were married (Nov. 2008), I've been in the ER twice, and had an ectopic preg. scare - 2 vaginal sonos and hcg blood work twice.
Our bills have totaled well over $2,000 so far, and we haven't gotten bills from the ER trip for pre-term labor last weekend. My husband doesn't make very much, but we HAVE ins.
Long post - I know...but all that to say this - Insurance has good points and bad points. You have to weigh the benefits and risks for YOUR family. I know many, many families who do not have ins, and they take care of themselves as much as possible. Then when something does happen, all of them find a way to deal with it.
I hope you will know what to do...these decisions are not easy.
