I need a bike

We got our daughter a bike for her birthday and she is getting very good at riding, though she still has training wheels. It makes me want a bike of my own, one I could pull our son around the neighborhood. The problem is, bikes are expensive. I have seen a lot at some of the pawn shops, but I'm not sure how good of a deal that would be, and if they would need reconditioning, which I don't feel like doing. So, I'll hit craigslist and find nothing and scout out new bikes to see what I want and how much it is and stay in this "wanting" place for a while longer.
