Forster custom shop will open up the neck dia to your specifications for $12. Unbelievably little run out is the result. I know of a Bullet tester for Berger and 1000 yd match winner that uses this system of having Forster open up necks to the dia he likes. He looks for run out .0001-.0002 on loaded rounds.
Forster and Redding also sell the sleeves for the benchrest seaters that are blanks,gunsmtih can chamber those sleves. The forsters that I have reamed cut like butter.
Forster benchrest seater, lee collet die with various sizes of mandrels, and Redding body is going to be a hard combo to beat.
If you are shooting some longer ranges, verifying your run out with A particular pattern of reloading is a priceless part of your own QC.
I have found presses, shell holders-twice, and a host of sizing dies that went in the scrap bucket.
Whidden dies, Harrells dies are top grade custom dies that do not break the bank, however calibers are limited.
For a guy just wanting a standard set of dies, the Forster set with a neck sizer is going to be tough to beat. Few understand how the expander ball is pulled though the neck while a portion of the neck is still supported in the neck part of the die. This supported neck while the expander ball comes through the neck keeps the neck from being kinked out of alignment.
Also, using a very slight trace amount of water base lube in the neck, Lee Sizing wax will allow the expander ball to come through the neck with the slightest ease. Also, the water base lube does not contaminate the powder and cause powder to stick when you dump the powder in. The use of the lube in the neck in conjunction with the Forster dies pay big dividends in getting run out to .002 and less with LITTLE EFFORT. Remember, a trace amount on a Q tip is all that is needed.

In summary, if you wanted simple life on the die purchases, then go Forster, and if your caliber is not available, then go Redding Deluxe three die set.
Then brush your neck, lube with lee sizing wax, you will have some very uniform ammo.
NOTE: standard Forster neck sizers can be used as "shoulder bump dies" because they have the cartridge shoulder angle cut in them, no other standard production die maker does this. More often than not, the shoulders need to be bumped back instead of the web being sized down.
