While the Rock-chucker is a great press in it's own right, if you think you're going to stick with reloading, I highly recommend just ponying up the extra cash and get a Forster Co-Ax from the get go. No shell holders to buy for each caliber, great precision, and 100% repeatability when you swap from one setup to the next and back again, with the slide in dies. Only need to set them up once.
I've used all the major brands of dies, and have settled on 3 brands that I'd ever buy again. Forster, Redding, and Whidden Gunworks - for odd calibers and custom stuff, they are extremely similar to Forster dies.
To each their own but the advantages of the Co-Ax are hard to ignore, and if you do decide to get out of it, you'll get nearly every dollar you spend on it back in short order.
