Thanks, everyone, for your suggestions.

Thanks for the list Trek420--that will be a good starting point for me.

So, what's the deal with steel? Does it absorb shock better? I have been riding for over 3 years now, but I'm not a bike expert. I just get on my bike and ride. Steel is heavier than aluminum, so, does that affect performance at all? There seems to be so much emphasis on bikes being lightweight.

Muirenn- I'm on the Left Coast, in So Cal. But if you know anyone in my area that is looking to sell a used or past-model USA-made bike, I'm interested. I'm 5'7. I haven't measured my leg length in a while, so I forgot what it is. My hybrid is a 17" and the last time I tried to get fitted for a Trek road bike I *think* I was a 50 or 51 cm.
