I think old tech is better, it just needs some quality to go with it. Many people blame the fact that old machines (some of them, not all) break down more than newer ones, and don't last as long (mileage wise) on the old technology, when it was really caused by poor quality materials and poor build quality. New technology does indeed break down, and when it does, it is a lot harder and more expensive to fix than the old stuff. I work on newer vehicle electronics 40+ hours a week, nobody can tell me it doesn't fail. Technology in cars has reached the point where they are not really even cars anymore. Owners can no longer work on them. So far with bikes it is pretty much confined to FI, ABS, and sometimes some type of electronic suspension control. And nobody can say the Japanese bikes of the '80s were not stone reliable.
I won't spend more on a bike than I think it's worth, but if it's a good deal, I don't seem to have a problem buying bikes I don't need.
