I've used only Lee presses and dies
I started out in Jan. '07 with a Lee 4-hole Turret in a Deluxe Pistol kit to load 9mm and .243. When I discovered I could not use auto-indexing for the rifle rounds due to the too-short OAL capabilities of the press, I sold it and got the Lee Classic Turret and have been a happy 'loader since.
As I expanded the calibers I load to include .25 acp, .380 acp, .38/.357, .44, and .45 acp, I simply bought more turrets, set my dies precisely, and stored my dies w/turrets in the cylindrical storage containers that Lee rifle dies come in. This made changing calibers on the press quick and easy.
Then I got into depriming, sizing, and priming my .243 brass in large batches, so I bought a single-stage, older Challenger (pre-breechlock) for batch procedures. On the Challenger I use the Lee Universal Decapping Die, my .243 full-length sizing die, the Lee Auto Prime II, and the best bullet puller ever made -- the Hornady Cam-Lock Collet Puller.
On my Classic Turret I use a .243 Lee Collet Neck Sizer (with no depriming pin on the mandrel), the Universal Rifle Charging Die with the Lee Perfect Powder Measure (with a homemade spring return), an RCBS Competition Bullet Seater (shortened by a half-inch off the bottom), and a Lee Factory Crimp Die, all semi-permanently set up in a spare turret.
For all my pistol dies except .25 & .380 acp I use the 4-die Deluxe Carbide Pistol Dies which include the Carbide Factory Crimping Die in either taper or roll crimp appropriate to the caliber. I can reload pistol calibers at the rate of about 100 per hour, not the fastest compared to a progressive press, but the resulting ammo is consistent, and plenty for my shooting pace.
Because I not only have a Mechanical Engineering degree but also am on a fixed income, I am therefore somewhat of a tightwad and very picky about quality and value. I have never regretted choosing mostly Lee equipment and accessories, and I personally recommend Lee for any reloader, beginner or advanced.
