Cartos are a funny challenge. Everyone likes different things. I prefer the pre-slotted variety, as they're the only ones that can keep pace with me (without dry hits or burning). My preference is IKV, but I also find Boges quite acceptable.
The cost of vaping starts high, but then greatly lowers as you progress. In almost 2.5 years, I'm now exactly at 65% (two full-time vapers in the house) of what I would have spent on smokes, and I've gone hog-wild with purchases. With just a bit of self-control, that number would be much closer to 30%.
The blue line (below) is what we were spending on smokes, averaged monthly. The purple/pink represent our actual vaping expenses (closely monitored).

Point being, don't let the early costs deter you. Once you find your groove, you should be able to save a ton (if you don't follow my lead).
Good luck, and I hope you hang in there. The ride is well-worth it (at least IMO).
