One of the best things I did was to buy a drill sharpening gage off of eBay. Not only does it allow you check the angle you are grinding but also the length of each cutting edge.
This was about $7. I could probably get a new one cheaper but this one has a bit of history attached. I think the Union Twist Drill Co. no longer exists, as I couldn't find anything with a quick Google search.

On the weekend I broke a 3.5mm drill and was able to sharpen it to finish off the job. I'd certainly have to put on the magnifying lenses if I wanted to sharpen anything smaller!
