I'm reading that price for the unit correctly? Nearly $45?
After conversion to USD, yeah, looks about 42 or so, with free shipping to the states. A lot less than the competing electric generators I've seen so a good deal I think.
Of course you need a container for the smoke, but that could easily be an existing grill or smoker, or even a cardboard box. I use my Weber Smokey Mountain or my Weber kettle grill.
One nice thing about cold smoking grain is that no 1, I won't have to worry about losing diastatic power in the malt, and no 2, there's no need to wet down the malt if the temps aren't rising above room temperature, so I don't have to worry about burning the malt, or roasting it too much, or not getting it dry.
