we're putting one in at the minute. Can't remember the manufacturer, but it cost €280. Couldn't see the big difference between it and the Stira to be honest; after all , it'll spend 99% of the time in a dark attic.
word of caution on the €100 euro ones (Woodies stock them):
They are only available in 'one size fits all'; however, the ceiling joyces in modern houses are different widths, either 56, 57 or 58cm apart (according to the carpenter).
The expensive (dolle, spaire, etc), come in specific widths for your speciifc house; making the Dolle type ladder seem like the best option, for fit and value.
