Hi there. I'm looking to buy a Bianchi, Or perhaps a Cannondale Bike. I dont mind a used bike at all. I dont need the greatest bike on the planet, but would like to know the difference, and say ranking between some of the many models the brands make.
For example, I've learned the Brava is the entry level Bianchi, but what about if a seller says this "1970's or 1980's Eduardo BIANCHI Piaggio Racing Road Bike Vintage Campagnolo Everything" with ""Nuova Racing 12 Vel." Written on frame". how good is this bike? what is a fair price? and what about the many "Bianchi PREMIO's" i see. where do they rank in the line-up? what would be considered a fair price/great price. Again, i'm not looking to get any of these bikes brand new. I've ridden regular road bikes for a long time, but never got into the culture or discussions. when one was used up, i simply baught the next $50-$75 model i found in the paper, etc. I'd like to get something really nice, but yet put in the work/time to getting the best deal possible. Only I need to know the "lay of the land" first, so i know what i'm trying to go after, and what not.

any etxra info would be greatly appreciated. Thank you so much!
Cheers,
David
