I don't know what paint you regularly use, but I would stick to using the cheap air brushes if you use Badger Model Flex. I think it is probably better now than the first stuff they came out with, but I understand it still has a tendency to set up in the gun before you can finish spraying. It isn't particularly hard to clean out an external mix, single action gun, but the internal mix, double action gun can be a real problem as I understand it. I noticed as I read through Josh's thread on painting the MET, that Dr Wayne recommends using the double action air brush with acrylics including Model Flex. If you read through that thread, you will get a lot of good information including some really good info from Wayne on how to avoid having the Model Flex dry in your air brush.
