Just purchased a Extend & Climb ladder today, I know you can probably get them a little cheaper on-line but we happen to have a Sherwin Williams paint store right near us and they are a dealer.
They had the 12.5 type II which is rated for 225lbs on sale for $175
It will work perfectly for our needs, already checked out the roof on our ML23fb and it will make cleaning the bow window on our raised ranch house much easier.
Model# 770P 12.5
Amazon has them for $168, so I guess we got a decent deal.
