I had one for years, it's the best vape I've ever tried. If I where buying one today however I'd go with something better, just because if I'm going to spend so much on a vape I don't want it to be just as good as something I had 5 years ago. Volcano is still probably the best vape =>$500, you might get bored of it after a few years like I did, but it'll be worth the investment and when you're done with it you can resell it for half it's cost.
Only issue I ever had with the Volcano is that it's loud af. People in the room beside you will be able to hear you inflating a bag, if that's an issue for you consider a Plenty, that was my biggest issue imo. Bag's still really nice for certain times though. Plenty is almost as good, but it's smaller, cheaper and easier to use stealthily.
If you're wild rich consider buying the Orion Project, no one that I know has ever bought it but it's from an extremely reputable company. It's $1500 but it seems to technically be the best vape on the market. They told me they plan on releasing a full product in more than a year from now, and that'll be cheaper, but if you want potentially one of the best vapes in the world, and definitely one of the most unique, consider this.

So yea, if you want to save a little more money get a Plenty, if the Volcano is the perfect price range for you then get it, if you have a lot more money to throw around consider a Herbalizer or Orion project, which both work similarly but have some benefits over the Volcano.
