Hi. I'm mainly a commuter, and I commute frequently. I've been wanting to learn more about bikes but it's been slow. So far I've owned two big box store bikes. One was actually a pretty decent commuter, and the other made me realize how much I prefer a rigid frame over suspension for commuting.

Now I think I'm ready to buy some quality vintage bikes. Previously the bikes I owned cost all of $50 at yard sales. I'm looking to invest up to $250 for my next bike, but the range of choices is bewildering!

I was wondering if the more experienced folks could chime in. When it comes to vintage bikes, are there particular makes and models that stand out as "classics"?

I'm looking for ideas of which bikes might be called classic in the following categories:

1. Vintage road bikes that felt high performance even at a modest price

2. Vintage road bikes that accepted a fatter tire

3. Versatile vintage bikes - eg, I'd put the Bianchi Volpe in this category, based on limited research

4. Vintage mountain bikes - I'm not concerned about this category because, very broadly speaking, mountain bikes kind of perform w/ similar characteristics when fitted with slicks and turned into commuters.

I know I may be asking a lot here, but I'd greatly appreciate any info at all. Thanks.
