Decided to do this in 2 parts.
The Hornady Lock n' Load
Pros:
-The powder measure is terrific. It's accurate, works well with all the powders I have tried in it(the only occasional hick up is when you have to apply a small amount of force with extruded powder to "cut" a kernel of powder caught between the cylinder and the housing when it is rotating.)
-the priming system works well when clean (though there are a couple quirks I will get to in the Cons)
-the die bushings are a terrific idea and they are more adaptable to how you want to set up the press.
-it has 5 stations
-the powder drop die in conjuction with the bushings is a better idea in my opinion, as it's easy to remove to empty or fill, and if you have 2 measures one for large drops and one for small, it makes caliber changes really quick. And it's easier to adjust to the correct height for the cartridge you are loading than the Dillons Set up. (I have felt the need to purchase a powder die for every caliber I load on the Dillon. Not so with the Hornady.)
-auto indexing is nice
-the dies in the bushings can be stored in the plastic Die boxes from the following brands: Lyman, RCBS, Hornady of course, Forster, and even Dillon. (The Redding boxes can't close properly with the bushings installed)
-Their customer service is excellent and have never charged me for a replacement part and even pay the shipping no questions asked.
-The case retaining spring that goes around the shell plate, though maybe not as durable as the locator pins on the Dillon, the spring ring makes taking out and put in back cases at any given station MUCH quicker. I like this feature.
Cons;
-Powder slosh on mostly full cases happens regulary due to the shell plate Indexing and snapping into place on the ball detents, sometimes even on cases that are not close to full depending on whether it's a bottle neck cartridge or not.
-the priming system gets hung up if a kernel of powder or other debris gets into the primer slide track. This can be extremely irritating at times.
-I had to epoxy a hard plate under the priming ram. A dimple developed under the press and it no longer was able to seat primers flush to the case head until I did this modification. Now it works great.
-the ejection system hung up on certain cartriges. I tried to modify it with a file but didn't do much good. I have to push one out sometimes with my finger.
-the indexing Palls are i believe MIM. They can chip and ware out causing the press to go out of time. It can be adjusted to fix the timing but you have to be careful when it's indexing just in case you end up with a hangup so you don't break a pall. It's not really delicate, but I am on my third set of palls. I broke a pair on my learning curve, then a friend broke a pair.
-the shell plate comes loose after loading for a bit. This apparently causes some of the issues I have (many thanks to the post below) and can be fixed with a lock washer.
