FWIW if you choose Lee equipment, I highly recommend that you spend a few extra bucks and buy an Auto Disk Riser for each set of dies you purchase. Without the riser, the Auto Disk unit sits very low and can interfere with the dies, making it harder to adjust the dies properly.
Also, if you foresee loading more than one cartridge, you may want to spring for the Auto Disk Pro or the upgrade kit. The swivel adapter makes it much easier to move the powder measure without readjusting the expanding die every single time.
