Best basic, pressure-mounted gate?

Can anyone recommend a basic, pressure-mounted gate for occasional use? Sometimes I want to keep baby in the sunroom and out of the kitchen. I don't need to be worried about how easy it is set-up/take-down or pass through -- I just want to keep him out of the kitchen for 20 minutes or so. I'd prefer something well-constructed, but, of course, I don't want to pay a fortune.
Thanks

we bought the little cheepy Evenflo pressure mounted gate that is wood and plastic mesh.... it works fine... it's sturdy enough to take my eleven month old walkers abuse as well as our 3 large dogs!!! It was $11.00 at Target!!!
