If you're technical Mech mods are good for at home use and on the go if you don't mind carrying them around.
The MVPs are amazing devices, VV/VW makes them easy to get the correct flavor and cloud plumage out of tanks.
APV has the vamo v5 which I have heard nothing but great reviews on.
Nickoticket has amazing juice, along with Aliceinvapeland and MT. Baker Vapor has cheaper juices in high quantity if you're looking to stay cost effective.
RBAs are tricky and require a bit of a tech savvy person sometimes, but as people before me have said the Nautilus mini and most protanks are great.
Just try some stuff out post a bit more, everyone here can be quite friendly.
