Since this has deviated - I work in the car industry and human nature is interesting and often VERY irrational. When the price of gas goes up $1/gallon people go nuts and sell their car that gets, for example, 20mpg and they think they need to buy a hybrid or electric car. Unless the purchaser drives A LOT the annual cost would increase a few hundred $$ but said purchaser is willing to take a financial bath in order to achieve those precious MPGs. I could write a doctoral thesis on this mentality but people are what they are so they can part with their $$ if it makes them feel better.
Bringing this back to bikes - a Varsity, et al, is never worth more than $100 to me. I paid a bit of $$ for my recently acquired Legnano but the components justify what I spent. Also, old Legnanos are cool so I feel fine with what I spent. BTW - if someone has one of those old crappy Campy Sport rear derailleurs (1013/3), PM me!
