Well, I lusted after hi-end french stuff, and now I have several of them. I don't think I'd trade the '67 PX10 for anything much, except maybe another cool old bike. Love to find a 50's (or 60's) era Stella.

Keep in mind a lot of the hi-end older frames are handmade and silver brazed. If they're going after 30+ years, they are not liable to stop anytime soon. And the cost of comparable workmanship today is out of the range of bottom feeder of the economy types like me. So if other folks think old 531 bikes are worthless, it's fine by me.
