Yes it is worth it, BUT it depend on what you are trying to do.
I connected mine to the D.C. panel, to an open circuit. I did it over 2 years ago but I think I used a 10a fuse in the power cable & a 5amp in the D.C. panel. Easier to changer the one at the panel. Then I ran two wires to the helm to turn it off & on.
For me, I hooked up my VHF, GPS, AIS, fuel flow sensor & fishfinder. I wes much easier than dealing with the NMEA0183 wires.
On my new boat, I will be connecting the remotes to my deck though the NMEA2k backbone.
