I had the same concerns - picked up Doug's RSKŪ Mk5 and then was struggling with the best necklace. I decided on stainless steel beaded for the reasons others stated. Then I was going a bit mad trying to find a reasonable price on-line or elsewhere. Finally discovered my local Ace Hardware sells spools of beaded necklace and accessories (joiners, clasps) in a variety of sizes and metals. Look in the crafts section.
