fwiw,
The RCBS 2000 would be my choice. You can order the conversion for tube primers if you don't like the APS. I will say the APS system is SAFE and at worst you might have one primer go off. Though I never have in 125,000 rounds or so... Anyone who runs a Dillon long enough will have a ring on the ceiling above the press. The tubes can and do go up. They are thick enough to protect you as long as nothing extends over the top of the tube. However, it IS LOUD... I saw the rings for the first time during an unofficial tour of Nosler. They load daily test rounds on Dillons...
I really like the RCBS 2000. It is a lot of cast iron for the money. I figure it is likely the most I've ever gotten dollar for dollar out of any reloading gear. That said I started to buy a Dillon 650 when I was 19 until I ran into an EXPERT who had never loaded on anything other than an RCBS Jr. who talked me out of it. He did teach me how to load as a kid and hence held sway over those early decisions. In my mid-twenties I bought an RCBS 2000, along with the lock out die(Best money you'll spend) and starting spending more time shooting than loading. Honestly wish I'd bought the Dillon 650, however, the RCBS 2000 is an excellent press. Love the micrometer powder measure.
In the last 13 or 14 years I've loaded on other presses and regret not buying a Dillon Super 1050 from the start. Yes you have to pay for parts that break, however, it is in a class of it's own... I intend to buy one setup for .45 ACP and one for 9x19. I'll leave the RCBS 2000 for .357 Magnum, 44 Magnum, .454 Casull, .475 Linebaugh, and 10mm Auto... The ONLY way to run is a separate toolhead setup with your dies permanently installed AND with it's own lock out die for each chambering. The powder micrometer allows you to dial into a number quickly. A better design than Dillon imho... The only junky part on the 2000 is the linkage for the powder measure. When you get a 100,000 rounds or so through it, it starts to twist on extension. RCBS is just as easy to work with as Dillon. They have a NO BS warranty as well, however, it has to be experienced as they don't advertise. I literally had the lady on the other end telling me about extra parts I needed to replace when I called about the powder measure linkage. They sent a box of parts, with extras, and all at no cost... In short you won't be disappointed by either company...
