Recommendations for Dynavap Heat Source

Have had a Dynavap for 2 weeks now, and I really love it. Without knowing much about them I bought a 3 torch/fame lighter as the heat source.

Have been going through a lot of butane though. Have read that single torch lighters would be better. What are everyone's recommendations? Long term would I be better off getting some kind of wand?

Also, have I got this right? My experience before this has been a Boundless Vape + a Crafty+. To get a full extraction from these I'd need up to 20 minutes. With the Dynavap I can get a full extraction with 4-6 clicks in under 5 minutes. Does this sound right? Saving so much time with Dynavap.
