Love my genesis atomizers, collecting a bunch of sub-30 dollar attys. have a couple agat2s and couple rssts and an agi plus a few did and "cobra" clones. Out of all of them, my favorite RBA, that i own, is my "Z-atty clone" (not quite an exact clone (i believe the rsst is closer to a true clone of the ac9 than this is to the z-atty), it is just modeled after it). Absolutely superb, dirt cheap, better vape and easier coil to wrap than the aforementioned attys, and looks nicer IMO. It has a smaller wick hole than those more popular genny, around 2.2mm, but it hits as good, if not better. Perfect with my ss cable, 3/2 wrap of twisted 28g kanthal and air hole expanded to 5/64, though i am very tempted to go to 3/32.
I love this budget-vaper's setup (two tone kts+ flat top with black oring accents to match the rings in "z-atty clone" tank), which you can get for about 35 bucks shipped to your door.
