My brother uses a Harrells and loves it. I've used a Redding BR-3 forever.

Mark, you can modify your Chargemaster's settings with a few keystrokes. I love their convenience but otherwise they're agonizingly slow. When I load 7.62 or .338 Lapua in bulk I'll run two machines at the same time (I can drop the charge from the first machine as the second finishes dispensing and balancing).
