I'm also interested in your re-engineering effort.
I'm surprised about the problems reported with the RCBS. Mine has worked great, and I paid $5.00 from the bargin bin at Walmart (It was missing the primer tray, which RCBS was kind enough to send me at no charge).
I've used the Lee quite extensively and like it too.

Well, the Sinclair arrived today and my wife won't let me open it until Christmas! Is that mean or what?!!

I guess the excuse I used (i.e., Christmas Present) kind of back fired on me!

Well Thor now we know why the RCBS was trashed. I can hear the story to the wife now. "Baby Cakes that ole RCBS hand primer is just terrible and I don't think a Lee would do any better. We shouldn't let our son use anything but a Sinclair." Of course her reply had to be, "Well Sugar Bear I'll order you one today".

Well you can add my name to the Hornady column and here is why. I started out with the old Lee and I had one set large and the other small. When I could not find my large one I started shopping around. I liked the tray attached to the tool because I didn't have to handle every primer. I also liked the fact that the Hornady allowed you to position the tray to any desired position and used the same shell holders as the press which meant I didn't need to buy any Lee holders. The K&M and Sinclair tools, even though they are excellent tools, don't offer a tray option. So far it has work great for me. I have had an occasional glitch but nothing that wasn't fixed by a quick disassembly and reassembly in probably less than a minute. Don't get me wrong here the problems are so infrequent that I almost didn't mention it but in fairness thought I should. Even at twice the price of the Lee I have considered buying a second except that the change over is so quick, simply replace the ram and bushing when changing the shell holder, that I just can't justify the expense. Although, the other day when loading some 40 S&W I couldn't remember where the Hornady parts were so I used the prime seater on my RC instead. Another primer tool might be good but what if I forget where it's at .

another vote for lee autoprime, also I love there perfect powder measure for light loades of less than 15g.

I use the rcbs hand held tool.I have never had a problem using it.I don't know why others have had a problem unless they have it put together wrong.
