Another "Is Fuel Injection a Worthwhile Upgrade?" Question

Let's see for the price of two brand new Street Demon carburetors $600 on sale, the entire fuel side of my nitrous... $100 tank $200 + lines $150 fuel pump $50 pressure gauge $35 filter $35 low pressure switch..
Wouldn't need a window switch $55 timing retard $169 electric fan heat control $45... 2 step launch control can't remember how much...
Wideband O2 sensor $169...
Don't have a control for the AC idle switch and would have that.. certainly can't completely program all this stuff without a lot of hand work.. Jets metering rods springs for the carburetor and changing springs and stops in the distributor..

I'm assuming I can get like a stock Magnum distributor and I'm not sure about the ignition box?
If I could sell all that crap above for half the price I would be 3/4 of the way there...
