RCBS. Offer various models. Mine fits in my hand and doesn't move around like the Lee model did. The Lee also has much too slick a surface for my liking. After two weeks of using the Lee, I gave it away. The quality was another concern, but each to his own. The RCBS does cost about twice that of a Lee but IMO, is much stronger built and dependable. You also need Lee Shellholders for the Hand Primer that are different than the Shellholders you use in the Press. RCBS uses the same Shellholders in both. Price sometimes shouldn't be the only consideration. Go look at and hold each of them and then make your choice.
