I own over 200 vapes. LOL OCD issues.
Not too many vapes do herb and concentrate very well. Usually, they want you to use a pad or cotton. Yech. You might consider 2 vapes. One for herb and one for concentrate.
What are you looking for? Portability. Banger or e-rig style? Desktop?
Coils OK? Personally, I hate coils but the Terp Pen, for under $20 is an awesome concentrate device. I just bought a Kandypens Oura and I really like it, too. Basically, you have a choice.... coils, ceramic cups/donuts and quartz cups. Quartz cups clean up nicely. Coils and ceramic don't (IME).
So, depending on what you want, I might be able to point you right. Plus, the 420 sales are everywhere so now is a good time.
I just recently sold over 50 vapes at FC or I would sell you one of mine. Getting ready to move and I had to thin the herd.
As for dry herb vapes... for the money, nothing beats the Healthy Rips Edge for performance.
