I like both tsg68's and tardis's lanyards for other purposes (both are very well made) although for my neck-carry Arc AAA I prefer a stainless steel chain that comes with those "medic-alert" necklaces at any drug store. Cheap, durable, comfortable, and they don't itch, get dirty or stay wet when you play, sweat, or shower.
For me, the other two lanyards are wonderful for things worn "outside the shirt" -- digital cameras, GPS, larger flashlights, etc. etc.
Just my $.02
