have you thought about a medical discount plan? It's not insurance, it's just a discount plan for thing slike dr. visits, labwork, and meds. My DH and I used it when we were finishing up college and didn't have health coverage. for both of us it was under 50 bucks a month and it was cheaper prescriptions.
This is the company we used:

Mods, if I wasn't supposed to link that, please delete and I will pm it to the OP.
The customer service reps were very helpful.
I also had pre-existing conditions.
It's something to look at anyway. I rarely went to eh dr. but was on several meds at the time.
edit: I just wanted to add that you should thoroughly explore all your options. Whether it be insurance or discount plan or whatever, read the fine print.
