One could say it it's matter of personal opinion. If you're doing a few every so often then dipping is probably the easiest, fastest method. I found after baking that I was getting way to many cone heads on the thicker cs powders like black because of error on my part. So, I decided to tinker with a fluid bed build.

It's not perfect but it works for me. I think the total cost was under $30. Two or three plastic spoons of color gives me enough powder to work with. After I use a color I just pour the rest back into the jar, unscrew the union, wipe it out, and I'm good on the next color I use. I did add in the brass flow valve later on to get better control with a few of the candy colors. In all, it just takes some experimentation to see how each color will behave.
