I just picked up one of these Lee Deluxe Quick Trim tools with a 223 die since I've never had to trim pistol brass before. So far I've used it on about 400 pcs of 223 and I have to say it works and works pretty well. After getting a feel for it and making a couple adjustments I also have to say that it is down right consistent if I do my part. May not be the fastest method but It will do what I need to get done. Oh and BTW this is the hand crank model and not the one that attaches to a drill.
