Altsmoke.com - The BB, need to find your own batts for 6V
Adaptever.com - The Adaptever, Need the sleeve for 6V
Nhaler.com - The Xhaler, don't know to much about it but it does do 3.7 & 6V
Atmosusa.biz - The Copper, probably the cheapest 6V device that isn't a plastic box
Only company I have personal experience with is Altsmoke. They had it to my doorstep in 3 days. Any of the companies I listed will definitely be able to get it to you within a week though
