Where Can I Find Basic And Cheap Health Insurance?

I am a 25 year old part time college student looking for very basic and cheap health insurance. I had prior insurance under my father’s plan but was dropped when I turned 25. Legally I can elect COBRA continuation coverage but the monthly cost is above what I can afford. I am looking for cheap insurance that would cover doctor visits and prescriptions. I am not very knowledgeable about any of this; any advice would be greatly appreciated.
