As you see, there are plenty of recommendations for the Dillon, a fine press (or series of presses). For a high-volume or commercial reloader, the higher-end Dillons or custom commercial machines are the only possibilities.
For an individual reloader, there are other choices. Here is a link to a very thoughtful comparison:

I recommend that you read this and other evaluations, then try the units for yourself and make up your own mind.
About 3 years ago I bought a (barely) used Hornady LNL AP with auto case feeder from an older gentleman who was retiring from the shooting/reloading scene. The press has been outstanding and a good fit for what I do, which is loading .223 and 6Hagar rifle cartridges for highpower competitions. Most users of progressive presses load for pistol; I don't - I load only for rifle. I need an accurate powder measure - accurate enough for competition rounds. Quick change-over from .223 to 6Hagar and back is important - not just for dies, but also for the case feeder (and its drop tubes) and powder measure. Another feature that I value highly is easy adjustment of powder loads and reproducibility of various powder load settings.
Be careful to compare apples to apples. The lower-end Dillon is not a true auto-indexing progressive press - you must manually index. When comparing cost, be sure to include the automatic case feeder price in addition to the press. Think carefully about what type of reloading you do. Loading for pistol rounds is quite different from loading for rifle rounds. Some need to change frequently from one caliber to another; others don't.
I am not in any way criticizing the Dillon!! No flames, please! But - there are some differences between the Hornady LNL AP and the corresponding Dillon (the XL650, I think - check it out for yourself). The Hornady press turned out to be better for my needs, at a better price, too. Dillons are fine presses (as is the Hornady press) but there is a certain "Dillon or Die" crowd that tends to dominate the discussion. Dillon has a fine reputation, but an individual reloader would be well-advised to do thorough research. There are nit-picky details in setup, adjustment and changeover from one caliber to another that make a big difference in the suitability of one brand of press vs. another. It's hard to know about this until you actually set up and use the presses.
