I haven't used both but I can only say that my vague, non-noncommittal, gut feeling from what I've read is that the RCBS is a better unit and worth the money. I wouldn't argue the point, as I said it's just sort of my unintended, almost unconscious perception of what I've read, but it seems that way to me.
Still happily answering to the call-sign Peetza.
You do not HAVE a soul. You ARE a soul. You HAVE a body.
He is no fool who gives what he can not keep to gain what he can not lose.
