In my browsing of propane burners to fire my boka work in progress I have found some are high and some low pressure. I am not sure I completely understand the distinction between the two for practical use. I currently have a burner which I assume is high pressure due to the roar it makes, which came out of a fish fryer. Which is better for our applications? Am I correct in assuming low pressure burners would save on fuel cost, but have a longer start up time? What do most folks typically use.

I have tried to google this on the site, but have come up short. I have a feeling it is out there and my google-fu isn't strong tonight.
