Suffering a little "sticker shock" here. I have been using a plug tray from Champion for many years. Too many holes, but hey, I used to own a 182 and a Baron. Glad I looked at today's price before suggesting anything... $52.29 (plus shipping, of course.) A little time with a piece of scrap and a drill press looks like a real good plan!
