As part of an updating of my 30+ year old kitchen, I want to replace the (crappy annoying piece of junk) gas cooktop I have been suffering with for umpteen years. I have no idea where to begin this quest. Looking for advice on how to choose; recommended brands; personal experiences. Do not need fancy - just want something that will give me good heat and burners that will freaking well light when I turn the knob. Price, alas, IS a factor. And it must be available in Canada.
