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.
