Nutrimill backup recommendation
so I have my Nutrimill and am still pretty happy with it. The problem where it was leaking a small amount of dust lately was, I think, due to me setting it just a little to fine. Moved the dial over just a smidgeon, now we're golden.
HOWEVER, since I am planning to bake for the Farmer's Market, I have a slight concern about the possibility of the mill failing, for whatever reason. If anything breaks, I know I can send it in, but I'd literally be out of commission for three weeks or more. So, I'm thinking about getting a second mill to have on hand, just in case. I like the Nutrimill and might just buy a second model, but am also curious what others might recommend.
I mill about 20 pounds of red hard spring wheat berries at a time, with the occasional rye for my starter. Noise is not a big issue, speed and capacity are pretty important.
Anything else I should look at before giving Pleasant Hill Grain a call?
BTW, I just saw they now have an attachment  that allows you to mill directly into a Ziploc style bag. I'm waiting to hear back from them if it would allow me to mill directly into the bucket, since the bags are most likely still too small for my batches (around 5 pounds per recipe).
Thanks for any suggestions,
