Hi,
Like many here, I have not used the Safety Prime tool. I do have a Lee ram prime tool in case I should suffer the same curse that got Weshoot2 and I break both my Lee Auto-prime tools in the same day...
Personally, I'm among those who prefers a hand tool to other systems. Whether it's a Lee or RCBS doesn't make that much difference to me. If it's a Lee, be sure to lube it per the instructions, or it WILL give up on you! The one I use most has many thousands of rounds thru it and works just fine.
This is one of those "many ways to skin a cat" things you'll find in the reloading world, so try a tool or so and see what YOU like! Fortunately, you won't be out much money if you don't like one or another...
