VHF Radio with AIS (receive only with built in display) about cheapest $250 US

AIS transmit/receive transponder cheapest $550 US. Requires an antenna (can share with your VHF antenna) and a display. Baseline cheap laptop maybe $400 US, baseline chart plotter maybe $1,000 US.
AIS units do transmit frequently so they do provide a load for the batteries but the load is inconsequential compared to the load from a laptop or chart plotter.

I expect that someone will come out with an integrated transmit/receive AIS in the very near future. I expect they already exist and are only waiting on FCC approval.
