We have a munchkin walk through gate from amazon, its pressure mounted and VERY sturdy, LO pulls up and wrenches back and forth on it and its not going anywhere. I love that it has a door in it so I can walk through and close it rather than take the whole thing down or try to step over it.
We have two of these...love them! Not sure why it got some bad reviews on amazon. But Babies R Us usually has a buy one get one 50 off, that's what we waited for!
