If all you are doing is .45's and don't plan on doing lots of small lots of others, look into a Lee Pro-1000 progresive machine.
They are $129.99 on sale @ Midway or somewhere. The press is already set up for a specific caliber as ordered (you need to adjust the dies for your needs, though). Comes with a carbide 3-die set with powder-through-expander, a powder measure, feeder, etc. Uses 3-hole turrets like the older turret presses. Only other stuff to buy is a powder scale and a bullet puller.
You *can* convert them to other calibers pretty quickly. Worst case scenario, you are going to a caliber that requires different size case feeder & primer feeder, and you don't have a 2nd carrier preloaded, it takes about 5 minutes including adjustments to swap the shellplates, feeders and primer sizes. Or, just buy a 2nd carrier and set it up for the 2nd calibre (For example, a 9mm carrier and a .45 carrier) and the swap is less than a minute. Cost for a complete 2nd shellplate carrier with all the parts, priming system, etc. was $35 plus UPS.
Obviously, get a 2nd die turret plate to set up the other caliber once and not again.
The three-hole turret press & the Pro-1000 take the same turret plates, they are on eBay all the time cheap.
I picked up extra parts so I can now change from 9mm to .45acp in about 30 seconds.
I can punch out 200-rds from my Pro-1000 in about an hour starting with tumbled brass.
Other than the basic press kit, options for a pro-1000 would include a collater funnel for the case feeder, and of course an accurate powder scale to confirm your load weights, plus a kinetic bullet-puller hammer to fix your mistakes.
Cabela's has a Classic Turret Press Anniversary Kit that includes everything you need to get loading, except the dies & bullet puller, for a very fair price if you are set on a turret press and not a progressive. $149.99 less dies!
http://www.cabelas.com and search for the Lee Turret Press kit. Comes with scale, powder measure, primer tool, etc. just add a set of Lee Carbide dies. (Carbide, because you won't need to lube your cases like with steel dies... highly recommended for pistol!!!)
Check out F&M Reloading in Ohio for great prices on Lee stuff. They run eBay auctions a lot, also.
