Biri,
Yep, the "free" shell holder is one of the things Lee uses as a come on.
As nearly as I could tell, I believe the Lee FCD you show is the collet type.
With the die shown, you would use the bullet seater in the standard 3 die set to seat the bullet and the 4th Lee FCD to crimp the bullet.
I have found the 4th step to be un-needed as long as a person properly adjusts the 3 die set.
Looking at your second link, it appears to show a standard 3 die set.
I read that Lee does package and sell 4 die sets. 1st die is sizer and decapper, 2nd die would slightly expand the case mouth and depending on proper adjustment, slightly flair the cast mouth to prevent the sharp case mouth from cutting lead from the bullet, 3rd die would seat the bullet and 4th crimp the case mouth.
The one thing I do not recall is, what kind of rifle are you using.
For example, on a single shot there is little to no need to crimp the bullet unless as I do, you feel that you get a bit better powder burn with a bit of a crimp. I shoot a RUGER #1 - 45/70
But, I simply and successful use the 3rd die of my 3 die set for both bullet seating and crimping, just as I have done for handguns for many years. This includes my 45/70.
I believe the third link you provide is the same Hornady die set that I use for my 45/70.
I have used Herters dies way back when I began loading, but quickly moved to RCBS because of the very pour quality of the Herters products I happened to get. Have used mostly RCBS dies for years, with some "CH" dies, Lee and recently Hornady thrown in.
Of late, it has been mostly Hornady dies that I bought new, but have come buy some other RCBS - new and used - that have been added to my assortment.
If you buy the Lee products, and yes the Lee dies I have used sized fine, buy some RCBS or Hornady lock rings to replace the Lee "lock rings".
That has always been a big negative to those dies for me as when I adjust a set of dies, I expect and intend that adjustment to stay as set until I see some reason to change. With the Lee aluminum "lock Ring" and "O" ring set up, the adjustment is always subject to being moved and can not be relied on to stay put.
If and when you move to loading bottle neck cartridges such as I think the 9.3X62 to be, you then deal with mostly 2 die sets unless you happen to be using cast bullets in which case something like a Lyman "M" die might prove helpful.
If your interested, send me a P.M. with your personal "E" address and I'll send you a document that addresses proper adjustment of bottle neck sizing dies.
Along that line, I have used "neck sizing" dies for bottle neck cartridges at times and NEVER found them to be an advantage beyond a properly adjusted set of standard "full length" dies.
Your getting there, and with all the questions your asking, I think you will get er done in fine fashion no matter what brand of equipment you go with. I do buy some Lee products, but am picky in that area, due to previous experience. Just pick and choose wisely and you will do fine.
:biggrin: Not everyone needs as I do, to take a Mack Truck to the grocery store. :flute:
