I have heard good reports about the drill doctors. I don't have one though.
I built the sharpening setup in the picture using a 1750 rpm motor with about a 5" sheave and then to that sheave bolted a 6" piece of MDF with pins sticking up out of it. The pins go into holes in another piece of 6" MDF that I adhere round pieces of sandpaper to. I have several interchangeable 6" discs with different grits of sandpaper on them. I use this tool to sharpen just about all my hand tools, chisels, plane irons, etc. I also found out that it works well for free-hand sharpening drill bits.
The finest grit of the discs is 600. After I sharpen a plane iron or chisel on the 600 grit, I move over to a diamond stone and then to water stones, then to leather strope wheel.
