I opted for Garmin AIS 300 for two reasons, it has a built in aerial splitter, and the ability to output AIS at 4800 baud. If you need either function it's £300 price tag makes it good value

That's interesting. My XB8000 which in all other respects is excellent can output through its NMEA port at 4800 or 38400 but if I switch it to 4800 is tells me that "AIS data will not now be outputted as you have selected low speed", or something like that. I needed the multiplexer to solve that problem!

I agree.

The OP does say "receiver" ...... but if he buys one with a built-in multiplexer then the complications are indeed, much reduced.

In fact, the McMurdo M10 Transponder (same as Camino I believe) can be configured with two NMEA output ports - one at 34800 and the other at 4800 which simplifies the additional components required. The additional cost of a transponder over a receiver may be the same as buying additional multiplexors to split the output into two separate streams which I think is what the OP wanted; Slow for the radio and high speed AIS for the plotter?
