I've had my RCBS Charge Master 1500 for a few months now and I'll be using it more once I start loading for my .405! The RCBS is well worth it IMO. It is also possible to tweak some of the settings in the RCBS to increase the charge rate without compromising accuracy, I'm sure Googling would find the instructions.
