Sometimes the el cheapo bikes are best. For my 3 mile commute I can choose between a 20 yo, 19lb Bianchi with Columbus SLX tubing or a 30 yo, 26.5lb Motobecane with Hi-Tensile 1020 tubing.
The Moto has a longer wheelbase and is noticeably more comfortable on the brick pavers downtown.
The Bianchi is what I grab when I'm in a hurry though.
