First, if they are brad-point, the Drill Doctor won't work. Second, given your statements, the only other options are to pay someone or buy new ones. (You can send your old ones to me)
Really, sharpening a standard drill bit only takes a few minutes and a little practice. Now that your are going to buy new ones anyway, practice with your old ones. I'm sure that if you take a few old ones down to the local machine shop, an old fart will show you how to sharpen them up and get you started.
BTW - The Drill Doctor does work fine. I gave one to my dad and he likes it. I however, still prefer the old (faster) way myself.
