It’s quite often that I feel like the rookie that I am around here, but I’ve read some of your other posts, and sense that you are a beginner buyer/seller as I’ve become. I love restoring bikes, but I can’t afford to keep them. I’ve yet to sell a bike without a new chain on it however. I can’t remember using any other chain than the SRAM PC 850 or 870 on any vintage bikes I’ve dealt with for the past 3 years. I’d like to try the KMC chains because they get such great reviews here, but they are not available off-the-shelf in my area, and I prefer to support my LBS’s when I can. Yes, they are more expensive. But, until I’ve experienced the wonderfulness of a $5 chain, I will keep dancing with the girl I brought to the Prom.
