I recently bought the small drill doctor. It was an eBay purchase, and I fully expected it to be junk, considering it was less then $35 shipped.
I was pleasantly surprised at how well it worked, how easy it was to get a good point, and how quiet it is. I took a nearly worthless 1/4" bit and with a couple quick turns had a drill sharper than new, which cut straight without any wandering. The machine came with a bunch of rings that are apparently some sort of adapters, but there is nothing in the instructions about them. I assume they are for split points. There is a VHS tape included that I haven't watched yet. That may shed some light on the rings and their use.
Since I got the model 350, it only goes up to 3/8" bits. However, I rarely use anything over that, so I'm fine with it. Based on what I have, I'd recommend getting one to anyone who uses drill bits frequently.

Full of ideas, but slow to produce parts
