This appears to be a model AA which is adjustable at both ends. Other mills that you are seeing for less money are likely non-adjustable or less adjustable.

I'd like to tack on a hops order:
1# Centennial
1# Columbus
1# Magnum
+ shipping/handling to 17050 if you're willing.
How are you handling shipping totals for pre-payment purposes? Thanks for going through the huge effort to do this!!!
