I went to my local hardware stor today to buy my dad a ladder for Christmas. I noticed they had a bunch of different ladders, who would have though this would be so hard. They had type 1, type 2. Then they had an aluminum ladder for $54 that weight 35 pounds and a fiberglass that wweight 25 lbs. for $125. What is the difference or can some tell me a little bit about the ladders. I don't know what to get.
