I would look hard at the used market - you can get an excellent used bike for $1,200.
For better or worse, the new bike market at that price point is not that interesting - you are basically shopping for fit, because nearly all the bikes will have an aluminum frame and similar components for $1,200.
Bianchi is unusual, in what I consider a positive way, in that they still offer a fairly wide array of steel bikes, which I prefer to aluminum for everything but pure racing (which I really don't do anyway). LeMond may also have some steel bikes that are fairly affordable.
Ultimately, I encourage you to do a lot of test riding, and make an effort, if possible, to ride a reasonable distance and hit some potholes, expansion joints, or other bumpy surfaces. When I sold bikes, years ago, most customers loved Cannondales on short test rides, but ended up unsatisfied with them for real riding - they were quick, stiff, and accelerated well, but were very harsh in real use over any distance. (I don't mean to pick on C'Dale, whose bikes have improved immeasurably in this area since - I'm just using them as an example.)
