Hey latex,
Just feel like giving my 2cents among the array of opinions that you will hear on this topic

.
Like many on ECF I have bought and used a plethora of RBAs and RBTs (DID, Oddysseus, Penelope, Zatty-U, Mark-T, Bully, and so on...), but one that stands out there as a cheap, awesomely built (Stainless Steel), EXTREMELY easy to build, easy to clean, and easily accessible is a RBA known as A7. This RBA can be used on top of a Reo as a bottomfeed atomizer (sorry, I'm unaware of other bottomfeed mods that can use an A7), and also as a regular dripping atomizer on most mechanical and electronic mods.
I never worried too much about tanks due to the fact that are very few instances that I need it them. If I'm driving I just attach my vapemate to my A7 and off I go. I always leave my vapemate in my car for such instances. I'm a dripper by heart, so tanks to ME are not a priority.
One of the biggest advantages of rebuildable atomizers, other than cleaner flavor (with the proper wick or mesh), and lots of vapor clouds (personally, I care less about this) is the cost of rebuilding one. I can literally build one coil PER DAY, and its gonna cost me less than $3.00 per MONTH !!!! People that use Genesis atomizers save even more due to the durability of the wick (SS mesh).
Also before I forget, another current "love of my life" is a RBA know as GP Spheroid. Also extremely easy to build, and to clean. A little more costly though. Around €89.00 if I remember correctly. This little guy does indeed put out a concentrated flavor that is seriously out of this world for a silica RBA. Nothing short of incredible.
Well, before I write a whole book here, latex, I just want you to know that you do not need an extremely expensive "delivery system" to be happy. Look at me, I'm happy with a $17 RBA (god, so much money spent

to get to this one). Once you find what you want, stick with it. Personally, in terms of RBAs, I think that this industry, right now, is a little stagnant. Not in relation to different RBAs, see, but in relation to what they provide. I'm not seeing much of a difference in Genesis atomizers at all, only very subtle changes to attain the same end--- a pleasureable vape.
I apologize for writing this much, and bid you luck on your search for your Holy Grail of vapes, latex
Take care, friend,
Nic
