Just to let you guys know my input, ive been in the "Cable" buisness for 8+ years and have climbed,carried,dropped my share of ladders, both Aluminum and Fiberglass. I went out and found the "CostCo" 17' ladder for $99. I gotta tell you, I love this thing. Aside from reaching higher than 20', its perfectly effective, (I'm 6'2" and 285 lbs.) This thing supported my weight very easliy, was light enough to carry everywhere, and given my 6'2", my reach height was far above the 17' mark, and I was still not on the top two rungs!
