First question, why are you using 123 to prime the ceiling. It is a great primer, but if you are not trying to block any stains, you are overspending on primer. Use a standard drywall primer, it is cheaper and will do just as well as 123. Second, Glidden makes a color changing ceiling paint that is far superior to the Behr. It goes on pink and dries white. It goes on pink so you can see any spots you have missed when painting the ceiling. It was designed specifically for the homeowner to fully paint a ceiling the first time. It is a good product that takes the guesswork out of painting a ceiling. You can spend more for ceiling paints such as the Benjamin Moore Muresco or Pratt and Lambert Skylight, but ceiling paint is still ceiling paint. The premium ceiling paints tend to be a softer white than a standard ceiling paint. Remember that the ceiling is there for looks, you are not usually touching or rubbing against the ceiling. High priced ceiling paints do a good job, but, in reality are not much better than the standard ceiling paints.

OK, thank you for the advice. I think I'll try that pink to white paint after I prime it.
