Here's a bone, my 2 cents worth...and this is IMO. Without going to an RBA/RTA/RDA as a noob, try a Kanger AeroTank or a Kanger Mega. With the new dual coil heads they came out with, flavor is really pretty good for a tank...you can get the Mega to chuck a fair cloud with the right juice, right coil, and setting on your current rig. If you want to explore further, again, IMO, head on down the Kayfun/Russian 91% path. Very easily rebuilt, I learned on my own with YouTube help. You can make your own coils, or buy them pre-made from several people on Ebay...my advice is organic cotton, wicks well, burns clean. If you want to move up further, buy the Magma (clone or original, you'll be hard pressed to tell the difference in most cases) as it has a decent sized well, not too bad for being mobile. The Magma is a flavor machine, the domed lid helps make it that way, the air hole ports directly beneath the coil...major advantage. If you want to take it one more step, I would recommend a regulated mod such as a Sigelei 30 or the KSD 30 or one of the 30 watt box mods out there. I prefer the KSD myself, but a lot of folks don't. It's fairly hard to mess yourself up using a regulated mod. If something isn't right with the way you have your stuff set up, it will flash at you and say naner-naner and do nothing, instead of going into thermal runaway.
Just my thoughts...I've only been at this for 7 months, so I am by no means a pro at this.
