Guzzizzit,
You're looking at reloading for 7 calibers and 2100 to 3500 rounds per month. That's quite a few rounds and suggests a progressive, but buying caliber conversions for all those calibers can get quite expensive, regardless of brand. You mentioned cost is not an issue, but when you get past two or three calibers, cost can be an issue, because you're getting into a couple thousand dollars with some presses at that point.
Since you're looking at reloading both pistol and rifle, I would recommend a Hornady Lock N Load as the progressive because of the superior powder measure and it's caliber conversions are simple and fairly inexpensive. And with the Lock n Load bushings, extremely fast to change calibers, which may be an issue if you're a busy individual.
You're not going to have inconsistencies in your rounds if you set the press and dies up correctly, so you shouldn't be too concerned with that. However, if you're going to be reloading rifle for long range, I would also recommend getting a single stage for those "odd jobs" such as decapping and swaging (CH4D makes an excellent swager that fits on a single stage for $20.00.) I use a Lee Classic Cast single stage for these tasks. Bottom line though, is you'll be out a good bit of money, even with the Hornady.
Right now, the best compromise going between price, quality and rounds produced for a new reloader who isn't sure if they're going to want to continue reloading is the Lee Classic turret press. Set up with a Lee Deluxe 4-die pistol set, a safety prime, a Pro Auto Disk powder measure and a auto disk riser (Raises the powder measure up to clear the safety prime.).
Based on your applications, I would consider NO other turret press, as most other designs are obselete (Big heavy cast iron bodies, but a single point of contact for the turret, allowing it to tilt and affecting accuracy.) and do not offer automatic advance, therefore quite slow.
The Lee Classic turret press has automatic advance for each die, but acts very much like a single stage in that you do one operation on one case at a time, so the new reloader can see what's going on and have good control of the operation. So you can produce 200 or better rounds of production per hour while seeing exactly what you're doing on each step, thereby learning the reloading process quite well.
This press is also quite affordable, with Kempf's gun shop offering the above setup as described for about $155.00 (make sure and click the option for Pro Auto Disk Powder measure) and includes a Lee 4-die set along with some plastic cartridge boxes. Pretty good combination for the price.

Add in the "extras" you'll need or might want and you're reloading at a good clip for $250.00 or so. Not a bad price to start and if you go progressive later, you can still use the Classic Turret to save money on caliber conversions for low volume cartridges, such as milsurps.
I own a Hornady Lock N Load, a Lee Classic Turret press and a Lee Classic Cast single stage. I use each for very specific jobs and I'm extremely happy with all of them.

Dave
