Let me preface my post by saying: It is better to only have to touch-up a
drill bit by hand. I touch-up every drill just before I use it. I don't
like to do a major re-grind by hand and use a cheap fixture from Snap-on
when I do the 50 ea. 9/32" drills in a multi-head when they get dull. The
little bits, 1/8", get tossed.

Learn to sharpen drills by hand, it's quick, easy and free

No doubt, this is mandatory to know. Do a google search with the author
"teenut" and bionic drill sharpener for the BEST ever discussion of how to
do it.

That said, a drill grinder does a better job of making both flutes the
exact
same length and geometry. If one side is different the drill will drill
oversize in most cases. I have a Darex M4 drill grinder that I use for all
drills under 3/4" - just as fast as by hand and does a perfect job. I do
"touch up" the cutting edge by hand or make nonstandard drill point tapers
by hand.

As to the drill doctor, I don't won one. There have been many many posts
with pro and con opinions. My conclusion is that this is a light duty
sharpener, probably worth the price, but don't expect professional
results.
