I have no experience w/ the Passport but I would be interested too. Currently I use the Bel-Vector 985 and it's good, but a PITA too. Driving to and from the meets this past weekend, it really really annoyed me. Every time I get near one of those speed detecting "your speed is" signs, the thing goes off for like a mile and a half before that. Bridges, it goes off b/c of the local stuff beneath it. But I can't turn off the X-band and the K-band alarms b/c the cops here still use thoses frequencies. So I just hang back and hope it is a false alarm. I'd love to get one of those scrambler things....let us know what you find...
