I don't agree with all of the Rivendell stuff, but...
Lots of people on here eagerly spend upwards of $3000 for any of the current "you too can be a racer" bikes that are outdated the minute the newer model comes out every year. I don't see why a person who wants a durable, timeless-design bike like a Rivendell couldn't spend just as much.
I don't see too many of the plastic bike lovers posting on here that they could have gotten an old one instead for cheaper. Bikes are no different than any other consumer good. You can always get something used for cheaper if that's what you want.
