The reason for the separate piezoelectric lighter is that the owner will feel extremely far sighted for bringing a backup lighter when the PE gadget craps out, and I predict it will, probably sooner than later. But at least you can throw it away, further reducing weight.

Like thee weight reduction? I would sell my soul for a 15% weight reduction! I am a very satisfied PR user -having had no trouble at all with instability or pot supports (I have avoided stepping on my PR, sagely figuring that it would not do the stove any good).

Good thing a birthday is coming up. I think I am likely to step up to the PR II.
