Larry: I think Trula has already decided to go with one of the larger Chocolvisions, so isn't looking for comparisons to other machines. I think she's just looking for comparisons between the Delta and the x3210.
Trula: I've only used the x3210, because I decided that (for me and my process) the extra features of the Delta wouldn't be worth it. Since I'm bean-to-bar and only need to temper a few different types of chocolate, I didn't need the extended temper mode, or the ability to store a bunch of different recipes. If you're making truffles or chocolate-dipped items usingvarious couvetures, those features may be more useful to you.
