         This old timer agrees...more heat is a good thing (please notice I 
said heat, not higher temperature).  Even back before I started using 
temperature controlled irons, I had an Ungar 47 watt soldering pencil.  It 
was kind of a pain in that not only did it have a lot of heat, but it also 
attained a rather high temperature...keeping it clean was a 
problem.  Still, being able to make a solder joint almost instantly is 
definitely a good thing.
