I would definitely 2nd the notion for AGA-T2 + SS Vamo. They look great together. The RSST looks really good on a Smoktech Natural, same manufacturer.
Discountvapers.com has SS Vamo and AGA-T2
Unfortunately out of stock at the moment on the Vamo, but definitely the best (IMO) vendor to get one from. They have the updated version with a proper brass spring that won't heat up like crazy.
VaportekUSA.com has RSST+Natural Kit <-- Amazing price
You might have to do a pre-order on the kit, but it's totally worth the wait. A mechanical mod makes an amazing tool for getting a coil to burn evenly. Worth getting IMO.
Note: I have all of the aforementioned
devices and use them all regularly, purchased from both vendors, and am very happy with the products I recieved.
