I'm always looking for fast and inexpensive case prep tools. My old drill motor converted to a case trimming tool works fine but is still slow. There is a new device on the market called World's Finest Trimmer. It's from a company called Little Crow Gunworks.
www.littlecrowgunworks.com . It fits in your drill motor and you feed the rifle cases in neck first. The brass trimmings are spun out the side. You buy one WFT trimmer for each caliber. They are $70 bucks each. Not really inexpensive but fast, accurate, and easy.
