new derailleur for vintage bike
 
I'm thinking about buying a new RD for my '84 fuji del rey. It's already got around $470 in upgrades; the only things that aren't new are the frame set, FD and crank set. The RD pulleys are getting wobbly, and I can't use my smallest sprocket because of vibrations on the pulleys. But I'm wondering whether I should get sora, tiagra, or just something cheap that works. For commuting purposes, the weight isn't a factor. I'm more worried about durability, longevity, and overall quality.

Does anyone have suggestions?

How many teeth does your biggest rear cog have? It it's more than 27, I'd get a Deore.

You might give this guy a try.

When I had to replace the dérailleur on my 73 Schwinn World Traveler I just got a low end generic one. Been working fine for the last three years.

Isn't deore a mtb derailleur?

Also, I don't really know how to gauge the quality of these low end generic derailleurs. I was reading some reviews on amazon, and one of the guys said the pulleys started to wobble after 1000 miles, which is about 7 months of riding for me. I don't want that. So that's why I'm curious on the quality difference between sora and tiagra, and how different are these generic ones.

The road vs. mountain derailleur distinction isn't real. I've ridden Deore and Deore XT derailleurs on my road bikes for years and they work fine. The pulleys last (for me) the life of the derailleur, maybe 10,000 miles. Sora and Tiagra are a step below Deore quality-wise. If you want the equivalent "road" derailleur, get a Shimano 105.

If you run (or want to run) a big ole' granny gear, get a Deore. Otherwise, Tiagra is, IMO, the sweet spot of price and performance for commuting duty. I don't really think there's anything wrong with Sora, either, depending on your gearing.

If it's just the pulleys, those can be replaced:
