The seller doesn't provide enough information about the Atala to give a really good idea of what it's worth. But my first impression is that price is pretty optimistic.
If you browse the older threads, I think you'll see quite a few with titles something like "help me pick the right bike off Craigslist!" where someone posts a bunch of links to bikes s/he's seen on CL and we reply which we think is the best deal... and no one has complained about the etiquette of that. So, if that's what you're planning, go for it. I'm not promising useful replies, of course... but worth a try. Good luck!
Spend a little time educating yourself (read some of the threads on this forum for example). The best deals don't last long enough to post the question: "Is this a good deal?" I think the price is optimistic as well, but the pictures are so lousy it is really hard to tell.
Also realize that many people search this forum and will scoop up deals while you are pondering them. Not really kosher, but it has happened around here several times.
Hard to tell for sure, but that looks like a Campagnolo Super Record group with Look pedals and 105 brakes. It appears to have double bottle bosses which would place it circa 1985-1987. fThe frame is probably Columbus SL, maybe even SLX. If I'm right, orignal price would be $1300 - $1700. Isn't that region pretty high priced? If so, price may be fair, depending on actual condition. The very small frame restricts the market, so the seller may be willing to barter. I think this one is worth a look or at least a phone call to clarify the component group and tubing.
