Here is my simple solution for an auger stand.  If you control the auger bit, the PHD can be easily mounted and unmounted.  Most frame-type supports are too complicated, and cost almost as much as the post hole digger.  This is made of 1/2" steel pipe, welded to a diamond plate base.  You could easily put this on a dolly if space is tight in your shop.  I have a large implement shed, so I wanted mine in a fixed location.  I used to struggle holding the PHD upright to hook it up, but now it's a breaze.  I have used this Rankin 9" PHD 301 for years and have drilled hundreds of holes.  The stand really helps.
