If I was picking one based solely on those photos, I'd pick the middle SS version because of the insulator on the switch.
The top one I wouldn't bother with at all because of the possibility of it shorting with a battery that's wrap doesn't fold over on the bottom.
Thanks everyone for your opinions on this.

The top one (Ehpro) is the mod that I ordered from FastTech, but it is now backorder, and they have been telling me for 3 weeks that there is a "production problem" that has delayed the shipment to them. Here is the link to the one I ordered:
$21.96 Mixed Caravela Style Mechanical Mod Full Kit - 18350&18500&18650 tubes at FastTech - Worldwide Free Shipping
I didn't realize it was a Ehpro mod until 'Muggs' mentioned it.
The middle one that 'VaPreis' mentioned has an insulator around the switch is available from FocalEcig. Here is the link to it:
$21.70 Caravela Sailing Type Electronic Cigarette Mechanical Mod - Silver (1 x 18350 / 18500 / 18650)
I have no idea who makes this clone for FocalEcig. Obviously, it's not Ehpro.
The Ehpro that is backordered from FastTech is stainless with a brass colored switch on the bottom, while the center one from FocalEcig is all stainless (no brass accents).
They both come with all 3 sizes of tubes. I don't know which one would have the
nicest finish or the
best etching of the Caravela ship logo ... so I am wondering if I should cancel my order with FastTech and order the all stainless model from FocalEcig (which is in stock) ? ?
BTW ... Neither FastTech or FocalEcig tell you who the manufacturers are on these clones there selling.
