Standard Horizon do a DSC VHF with fully integrated AIS. Here in Oz they retail for about $320. After spending another $70 for a multiplexer, we now have it integrated with our Raymarine chart plotter/radar.
Last year sailing up through the Louisiades at the foot of PNG, we had a major whiteout just before entering a small reef opening that was also the major shipping lane for cargo vessels heading up to Japan from OZ. We only have the AIS receiver but the cargo ship's particulars came up on screen, I hit the call button on the AIS and the phone rang on their bridge which scared the life out of them as they had not picked us up on their radar
The captain was extremely grateful for the call and we were both able to reduce speed and take evasive action as their massive bow came out of the squall high above us.
We love our AIS
