The MEC's and the RCBS Grand are nice loaders. For your volume, you can't go wrong. I had MEC's and Hornady's in the past. MEC's were fine, Hornady gave me problems. I use the Spolar Gold now with heads for 12, 20, 28 and .410. If you're into serious volume and quality of shells, Spolar is the way to go. With someone setting wads into the wad guide we can load over 1200 shells in a hour. That's with a manual unit. A hydraulic system can be added.
