I was thinking of leaving my employer's plan last year and I went to
www.healthnet.com They have all sorts of individual plans. For a male between 25-29, the rates went from about 70-150 depending on HMO, PPO, and decudibles but that is in AZ. Your location says Pa and I don't think they have individual plans there. They might be able to refer you to a company that does, however.
Shop around, you'll be surprised what you can find.
