I have quite a lot of gates (drawmer, aphex, estec and behringer). I don't have the Intelligate but the Autoquad. Although Behringer's reputation is not the best, it's worth checking it. The Autoquad works well! It's not as fast as the Drawmer (you easier get in trouble with clicks) but even better (and faster to set up) than the Aphex 622, which is ten times the price.
Thanks.
