2nd bike question

Ok, so a little background...I'm new to cycling, just bought my first bike about a month ago. It's a Jamis Citizen 3 that I use mostly for commuting and cruising around town, as well as riding along a bike path nearby for some exercise. I absolutely love the bike for its purpose, and I want it to be my commuting and cruising bike. In other words, I want to add racks and what not. But now the cycling bug has bitten me and I want a lighter bike for longer rides, fitness, etc (my current one is about 32 lbs). So I want to get a 2nd bike. Thing is, I'm really (REALLY) tight on budget, so I'm thinking of getting a used bike, possibly an older one, and then upgrading it slowly but surely over time. But I don't know much of anything about this stuff. So I'm perusing Craigslist and just want the advice of some more seasoned cyclists on a few that I saw today. Here are the links:

Any thoughts? Second question: how do road bike sizes work? For my comfort hybrid, I ride a 21" that fits just great. Btw, I'm 6'1, 190lbs.

Thanks for any thoughts/advice!

I am the same height as you, just a little lighter, and ride a 58 cm road bike. I wear pants with a 34" inseam. My arms and legs are a little long, but other than that I am pretty much average build.

Bike geometry and fit is a deep topic, but for most purposes it comes down to these:
- You need to be able to raise the seat enough that your legs are almost straight at maximum extension on the pedals.
- The seat should be adjustable horizontally so that you can put your knee over the pedal with the crank horizontal.
- The handlebar should be approximately at or below seat level, and approximately below your nose.
- Your back should be somewhere around 45 degrees from horizontal.

A lot of bikes deviate from that on purpose for specific reasons (triathlon bikes, comfort bikes, etc.), but that is a rough, general purpose, "get you in the ballpark" type setup for general purpose road riding.

A 58 cm road frame allows me to make the proper fit adjustments so that I work my body correctly. This both avoids injury and allows me to put much more power into the bike.

For better fitting either have someone fit you or get a book. Andy Pruit is a respected authority on health aspects of riding, and has written a good book on the subject. I would recommend such a book instead of a fitter. A professional bike fit will do more for your performance, but this is stuff you need to know and understand yourself for your own health.

My gut insinct is to go to a bike shop for a used bike. You can see it for yourself and it will have been checked out mechanically by someone whose body language you can read.

A lot of those really old bikes will have 27" wheels and will have drivetrains that are more or less obsolete. They might have worn out chains, gears (rear cogs), bottom brackets, hubs, who knows what. A bargain bike could easily turn into an expensive repair job.

When I refurbished my 20-year-old road bike I did the work myself and spent ~$250 in parts. But I had the tools and another bike to cannibalize from.
