[quote="GPSNavX"]I don't think you can find a dual channel AIS receiver for under US$450. Then you will still need a VHF antenna, A GPS receiver, coax cable, Keyspan adapter and power. The attraction of the SeaCas is the all-in-one simpliclity.

Yeah, you're right. I was thinking about a one channel unit. I got the NASA one and it switches channels pretty fast, it looks like. I already had a Keyspan and a GAM antenna, so they cost me nothing (this time). Had to buy a BNC adapter and PL259 plugs.
I took the whole set plus a USB/GPS and my Powerbook and a 12v battery down the nearest harbor and it worked great with GPSNavX, although I didn't have any large-scale charts. Was able to confirm that my car was in no danger of being hit by a 600' tanker.
