We have 3 evenflo wooden hard-mount gates for at the top of our stairs -- we have a tri-level home with 3 mini-sets of stairs (7-8 stairs each). We really love these gates! On top of being stain-able to match your woodwork, they have an easy slide out mechanism so that if you want to remove them after the kids go to sleep (or for a year or so between having toddlers where they are necessary) you can just leave the brackets in place but remove the gates. The mechanism is easy to open one-handed for an adult, but the pressure you have to exert while sliding the gate out would be too much for a toddler. Also, some of the safety gates do not suggest mounting in banisters, so if that is your issue, the Evenflo might also be a good choice - one of ours is banister mounted.
