Well, you don't have too. I'm not really on a budget, but I didn't go with an opus. If you can deal with a manual start/shutdown system, and not surviving cranks, just get a PW-type of power supply. DO NOT, however, get an invertor... these thing drain the last juice out of your battery, are very user unfriendly (need BIG cables and shielding and blah blah blah), will definately have more chance of introducing some sort of annoying whines or garbage into your sound/video signal and also will not survive cranks.
Also, If you're handy with (simple) electronics, you can build your own startup/shutdown controller, and you can spare $$$ on the OPUS.
