welcome to the forum, bongo.
bianchi and shimano 600 is hard to beat. but $1200? you can buy and build a lot of bikes for that. you could probably build up two incredibly beautiful vintage sport touring bikes for sround $600/ea. but if this one is in the cards for you, just make sure it fits like a glove and it doesn't need anything like a saddle, tires, etc... good luck, and let's see some pics!
