I'm a boring machine junkie and like them all, each for a different reason.

My best worker (and favorite machine) is a Millers Falls, the height of the machine and adjustable crank arm length makes a nice fit for my long arms and torso. It has good rigidity and the action is very smooth, my one minor issue is the depth stop can slip so I back it up with a small C clamp.

The Boss is another nice machine but it feels a little cramped compared to the MF and it's climbing gear is a little rough. I don't have an original depth stop for the Boss so it sits with a 3/4" auger in the "high speed" chuck for peg and J-bolt holes.
