Wes...the 5 gallon cans of C23 are $155 here also.
I use Renegade Pro 120N fuel. Last time I bought any was last fall and it was $17 per gallon if I recall correctly.
Tig...I don't run a separate fuel system for the nitrous. Too much clutter and a PITA in my opinion. I just drain the tank and refill when I get ready to spray it.
If you do run a separate system dedicated to the nitrous, a 1 gallon tank is PLENTY. It won't even come close to using half that unless you're spraying multiple BIG kits.
