We didn't get the $500 type, but bought a Werner Equalizer extension ladder, the best we could find. Feels much much safer than our original wimpy ladder, worth every penny!
I had to put off starting on the doors last Saturday.
Hope to be able to begin soon! Not quite so scared of the job after great information and encouragement here! Purdy brushes ready, supplies gathered...courage building.
Still going for the shed door first, then the basement...
