Good paint brands that won't break the bank

I was showing company products at an aerospace tradeshow last year and the booth next to me was a Sherwin-Williams aircraft paint distributor. We got to talking and I found out their aircraft paint is actually superior to their automotive paint (think about the environment aircraft are stored and operate in) - and the price is better. I'm seriously considering using it when my '69 Dart gets painted. Check out their colors online.
