It's interesting the different ideas. The same article that said 230 deg is the optimum temperature also said sous vide is the best way to go. But water boils at 212. (unless I flunked science class-a lot) I will look around some more. I've wanted a sous vide for a while. Still did not pull the trigger there cause they are expensive.
I did order the MagicalButter DecarBox. Looks simple enough-silicon box with a hole for temperature probe and a remote display so you can see the internal temp of the box.
What kind of machine did you get?
