Hey Goatku!
Welcome to ECF and congratulations for going two years on a V2 kit, that is awesome. It isn't about what you are using it's about what is working for you.
I do hope you will move to a more standardized 510 form factor, it will serve you well over the long term. RubyRoo suggested 2 exceptional kits at vapdojo.com, and I will HIGHLY recommend them for their customer service, they are exceptional. No one is perfect, but they go out of their way to make sure things are right when mistakes are made.
As far as variable voltage, I would urge you to consider it, as it doesn't add much to a kit's cost at all, but is well worth it. Once you have VV and start to see how much better you can make some juices taste, you will understand the joy of it. It isn't hard to figure out, especially once you start playing with it, and it doesn't complicate the vaping experience, but it can enhance it and make it even better.
Good luck in your quest to find new gear, there are a ton of options available, figuring out what will work best for you is the hardest part. I would recommend checking with your local shops to see if they have anything that looks promising. That way, if there happens to be any issues or problems, you can go back in and deal with it directly.
Thank you so much! I really appreciate your reply. I'll get one with variable voltage now that you've explained it. And, I AM upgrading after all.
