We have a guy here in town who does amazing work (as in, wins national contests for his fantasy minis) using enamels. We admire his work... but think he's crazy. >:D
Aside from the fact that using any solvent-based paint requires extra precautions (fresh air!), I use an airbrush, which makes those precautions both far more important and far more involved. I recognize enamels' usefulness in doing fine detail work (the blending that can be done... <sigh>), but unless that's your goal, stick with acrylic.
