I spent $1200 on liquids for my 'Cuda, but that was back in 2006.
PPG DP40 Build Primer Concept (Sublime) Single Stage (1 gallon) Plus all the required reducer and catalysts.
I was able to buy all of the above at an autobody discount. Considering that was 6 years ago, and paint prices HAVE gone up, I think your $1200 figure is good.
