Gordon,
I'm game. Can you suggest a specific quality chain?
I'm not big on specific brand names, but I usually end up getting Tsubaki. Just not the fancy nickel or brass kind. Best price in the past has been from
www.loudfastugly.com, but I haven't checked with him lately, so not sure on the current price.
Look around, though, and definitely look through the list of websites in the FAQ. For a 530, 100 link, non-oring chain, you shouldn't have to pay more than about $30.
