I would go for a vapor shark RDNA 40, you might not be ready for the nickel builds but you can use regular Kanthal builds until your ready for nickel. I recently purchased the RDNA 40 directly from vapor shark about 2 weeks ago. The Mod is awesome with a great quality feeling, and the wireless charging is a nice feature. I have a kayfun and a SquapeR with nickel builds and it is definitely a game changer. Just waiting on my second dna 40 (Vapor Flask) to arrive with my newly purchased kayfun 4 today. If your in this for the long haul, then definitely get a quality device.
