I've enjoyed the RCBS which came in the press kit. Changing the shell holders is not difficult once it has been done a few times. My only complaint is the seating rod will fall out if the device is inverted.
It has worked well enough, that I will look at the RCBS Universal Hand Primer whenever (if ever) I need a new hand primer.
A lack of planning on your part does not necessarily constitute an emergency on my part.
