This collection of 20 (2 sets of 10) variable sized micro drill bits is a good bargain at 8 bucks, in my opinion. I've bought sets like this where the smallest bit broke if you looked at it funny; I've been moving these around with my fingers, trying to see how much they will withstand, and so far so good. As someone who works with miniatures and customization, occasionally I need to drill tiny holes into small plastic parts. This set gives me a large variety of sizes, with a backup in case one breaks, for a good price at about 40 cents per bit. Happy with them so far.
