I found a beat up used Schwin on eBay that was local and got it for $20. I bought a new rear wheel, cog, lockring & chain from IRO and used a front wheel around the house. I picked up a Sugino Crankset and BB for short money on eBay. The new wheel set me back the most (I think it was $140 for everything). I figure I am in for under $200. It was a fun project and it is great to ride when I am out with the kids.
