Natural gas prices have been volatile and extremely expensive lately in the socal area. I thought about this too but it doesn't make sense for me. The safety aspect was by far the most attractive part. I think the BTU comparison is the best framework but just remember that the volume of natural gas will be higher so the torches and such may not act quite the same. I'm sure there's a reason Herbies have different port sizes for the two gases.
