Eventually I will likely get into rebulding. Presently I have a bit invested in tanks that are usually seen(bcc not bdc presently) where the one I will notice most often is that the menthol flavors always seem to lack on the output stage as far as the Vapor part while they tend to stand out.
For others depending on which one some put out well on just the 3.7v battery depending on the tank or clearomizer in use while still not seeing any cloud. The vape is much cooler however for those that do not like warm throat hits! Presently I am trying to custom blend certain flavors that produce the vapor with the menthol to get more out of those without getting into the DIY stage as far as ejuice is concerned at the 6-8watt range. Despite getting a 20watt Vamo V6 in the mail today I won't be in any rush to be a "Cloud Pleaser" by any means!
For those that want to "OC Cloud Peformance" there's out there now that will leave you speechless! Try 180watts of Vapor power and half ohm upto 4 ohms! SMY GOD 180 Watt Box Mod $129.00
For the advanced at rebuilding coils and looking for vapor(fire) power to scare your neighbors away...
this will work! They'll be calling the local fire dept.s when the vapor starts billowing out the place you live!
Now for keeping up on stuff like this I can refer you to two different places one for reviews including them also found on YouTube and another for specials on drippers and other things like you have there namely rebuilables. First some great reviews are found at 411Vapes.Com: Down to Earth Reviews
The reviews are in video form for the most part there.
The second site lists deals by various vendors on mechanical mods as well as rebuildable atomizerdrippers, custom made wood mod/ecig stands, accessories, you name it! Vaping Discounts
The front page there displays the daily deals that get posted where you would want to keep a watch for something you may want to grab at times.
