I have the Perfect Compact Coater. It's the smallest enrober the company offers and probably the least expensive enrober on the market. It is even more rudamentary than the Prefamac that Jeff Stern speaks of. I find that it is an excellent starter machine. It is a giant step up from hand dipping without spending $30-40k on an automatic machine. As my business grows, I will certainly look into getting a higher end machine such as a Selmi or LCM (my favorite!). With the lack of financing available for small business these days the Perfect enrober is an excellent compromise.
It is a rather simple machine that includes a blower, a detailer, and a polycarbonate shield (at least mine does). Just like Jeff Stern says, it is the talent of the operator that really influences the results. I am able to keep the temper going for 12-15 hours. Keep your heat gun handy, but so long as you keep the room around 70 degrees you should only need to use it maybe once an hour for about a minute or two. Learning the mechanics of how the belt, the blower, and the detailer work will give you the best results. The Perfect Enrober is a simple machine and you will definitely see all the mechanics in action which is actually kind of cool. Tempering in the machine is easy with the seeding method. Also, cleanup is very easy and you can easily enrobe in dark one day, clean the pan, and enrobe in milk chocolate the next day.
Using a wheel based enrobing machine can actually make you a better chocolatier. You learn to keep an eye on things and have an understanding of what is going on all the time.
So the bottom line is if you feel you need an enrober, but cannot yet afford a Selmi, Savy, or LCM (Lexus, Mercedes, BMW) definitely get a wheel based machine such as Perfect (Honda Civic). It will get you where you want to go.
