I am in the market for new windows and am leaning towards vinyl - low maintenance and I paint wood anyway (my sincerest apologies to all you wood purists). I live in Traverse City, Michigan (for those of you familiar with the mitten analogy - at the tip of the little finger). The brand that I am currently leaning towards is CertainTeed, the "New Castle" line, Low E. I have heard all the sales hype and now I would love some input (good and bad) from all you end users - the consumers! Thanks!!!
