Posted similar question in the mechanics forum but thought I might get more/different insight here (ie: I'm not TRYING to be annoying, lol). The Simplex derailluers on my Raleigh GP are shot. The price of old Suntour or Huret running gear on eBay about equals the price of some low end new Shimano stuff from my LBS (talking front rear, plus new shifters). Though the guy is into vintage bikes, he doesn't recommend old derailluers, says new ones have improved yada yada.
Is the new stuff better? Any reason to go with old stuff asside from looks? Might affect value, I suppose, but I think I'll be upside down no matter what when this nightmare *ahem* project is over.
Oh, and either way I'll do a new freewheel.
