I heartily recommend "retract-a-gate.com." Those gates are awesome!!!
Everything they say on the site is true: they are easy to install, one-hand operate, look really nice, totally secure, etc etc. We have two gates (rollers) and extra brackets for other doorways. That way we can just move the roller to another place without paying for a whole other gate.
We had to buy that kind because of an irregular doorway but I would use them anywhere over the kind that don't retract. There are other threads discussing these, too.
