16650 battery Mods?

[skjames19]

I have been looking high and low for mods that house a 16650 battery. The only ones I came across are the ismoka and tornado rcs. I bought the rcs kit, but I want something a bit more durable/high quality. Am I just looking in the wrong places or are there really not any other 16650 mods out there? I love this battery because of the life and because its thinner than an 18650.
