I have the grandpappy of the T-Mag. The newer press is "better" in that it has compound linkage. IMHO, nothing else is materially different. Meaning, I don't much care for it from a user point of view. Conventional turrets like the Lymans have all the disadvantages of a turret with none of the advantages of either a progressive or single stage.
Conventional TURRET presses have several disadvantages. The turrets are "springy", they must be or the head couldn't rotate. The die holes are virtually impossible to precisely index without some amount of off-set from the ram. If you load more than a single cartridge, changing dies is the same as a single stage, no faster at all. Changing heads is so clumsy and expensive as to make it a worthless idea.
The Lee Classic Turret is quite a bit better in every respect. The method of installing the turret head is different; quick, simple to do and it has little harmful spring. The head has an auto index feature that greatly speeds processing a single case from start to finish, with good enough accuracy for handgun stuff anyway. The interchangable heads are so inexpensive you can actually afford to have one set up for each cartridge you load for!
And Lee dies with their Factory Crimp Die, and shell holder, are a GREAT deal!
IMHO, mounting a powder measure on any press but a progressive, OR a Lee turret with auto indexing, is a liability. Use a bench stand instead.
