The weinmann concave rims were pretty decent. My favorite vintage rims were the Super Champion 58s for touring and heavy duty use and the Mavic Mod Es. Agree that the sealed suntour or wtb hubs were fantastic. I have several sets (sealed superbe, sealed cyclone, sealed xc pro) and they all spin as nicely today as when I first bought them after lots and lots of miles. I'm pretty the sealed specialized were just a rebranded suntour and they are also excellent. MKS still makes great pedals. I just bought a pair of the MKS lambda pedals that look funky but they are a really fine set of platform pedals if you want to ride with regular shoes.

My favorite vintage component is the stronglight A9 headset. They were fairly inexpensive and lasted and lasted and lasted. I grew up in a city that had (and still has) really rough roads (New Orleans is built on mud and it is impossible to keep the roads there in decent shape). It was a great city to test out headsets though. I've seen more than a few campy headsets come back to the shop pitted. This never happened to the A9s. You can still get a needle bearing one inch headset if you look around like this, http://www.rivbike.com/product-p/hsrd.htm.
