I don't have any of the items I mentioned but they are in my dream chocolate space along with a cooling tunnel and a walk in cooler to store chocolates.
You may also want to consider a spray booth area if you airbrush colored cocoa butters.
Do you use a mixer for making marshmallows and nougats? I have an old KitchenAid and live it but would consider the Bosch mixer (http://pleasanthillgrain.com/bosch-mixer-universal-plus?_vsrefdom=gpshop&gclid=CLjNqJT8kcsCFQouHwodLBcJLA) if I needed a new one. I think @tikidoc has the Bosch, along with a few other eGulleters.
