Right, I don't really need high-end. Actually, I'm pretty happy with my old-school Schwinn steel (Superior, Continental, Varsity, CrossFit and CrissCross).
I'm 240 lbs so not really interested in the carbon or aluminum frames. Chromoly is about as high-end as I need to go. Actually, the heavier frames will give me more exercise

.
I took a new Cannondale for a spin. That was on sale for $800.00. It was nice but not really nice enough to get me to buy it. I am looking at a couple of used Specialized bikes - Hard Rock and/or Rock Hopper...or something like that.
Most of my riding is on pavement or hard-packed trails so I prefer 700c wheels with hybrid or commuter tires. I will probably be upgrading my Superior. Actually, I already bought a Campagnolo Centaur triple crankset and bottom bracket.
Ah, I didn't notice you were in the Detroit area too. Good to know.
