So true Ed @Ed Winskill It is a slippery slope. I draw the line with push-button ignition. However, being open-minded about new ideas, I've been known to use a lighter, or occationally a match, when I don't feel like smashing rocks together.
personally I think the 123 has better flame control and a lower simmer I have the 123 and 123 R and I am planning on removing the 123 R's from my collection I have 5 max sievert stoves and 10 123's
