I'm going to be teaching a chocolate truffle making class and I'm looking for a larger, but still easily portable chocolate tempering machine. I have a Sinsation for home use and love it, but their larger capacity machine is a bit pricey. I was looking at the ACM Table Top Tempering Machine and was curious if anyone else had experience with this one. The price is within my budget and with a 6 lb capacity it should be good for a class size of 20 - 40 people to each be able to cover truffles with tempered chocolate. I would want to have the chocolate tempered before the class (since I won't be able to keep my eyes on the temperature while teaching) and then I'm hoping the machine is good at holding the final temperature so that it doesn't come out of temper. Also, what I like about the sinsation is the whole thing is automatic and dummy proof, so I'm also nervous about having to be responsible for controlling the temps on this one, but again if the machine holds the temps once it reaches them I'm assuming it shouldn't be a problem. Any feedback anyone has would be great. Thanks!
