About 6 years ago I bought a Lee Deluxe Turret Press. About 4 weeks later I sold it and bought a Lee Classic Turret Press.
The Classic Turret Press had a heavier ram and linkage as well as the press itself being heavier. Like said above, it also handles spent primers better and it's a better all around press for not a lot more money.
Also, the Pro Auto-Disk Powder Measure is MUCH better than the standard Auto-Disk Powder Measure. Again it's well worth the small additional cost. The standard measure uses screws that thread directly into the hopper which is plastic. That will soon become loose. The Pro uses threaded bolts with knurled brass nuts instead of screws. The Pro also has a "hopper off" for unloading the hopper without making a mess. The standard does not, you have to remove the entire assembly and pour the powder back into the powder jug instead of just dumping the hopper.
