For most of my adult life (assuming I ever was an adult) I collected reloading equipment. Mostly mould blocks and reloading presses. Just before I retired someone offered me what all that stuff was worth and I sold it. Figured I would never get that chance again. Miss it a bit but, well, I had decades of fun and got out of it in one nice clean sale.
Of all the presses, probably 60, I like the Star progressives best. Love is a hard thing to explain but I just loved those units. Had at least one of each including their straightline.
But when it came time to pull back and just reload, as opposed to collecting presses, I picked the Pro 2000 and the Piggyback III. Both use those strips. A Star's primer system, at least if you bought it new, was flawless but... The reason the Star's primer system worked so well was because Elord Mott build each and every unit and he knew what he was doing. Made the first one in the late 20's and assembled each and every one ever up till his death. (Star's made after that were, well, unfortunate). The machine wasn't without potential complications but given Elord skill most users never knew that.
The APS strip system is by far the best I've ever seen. The strips, however, are both the machine's strength and weakness. The strength is that they work very well. The weakness is that the primer part of the company hates making them so they keep jacking the price up. Originally primers in those strips sold for exactly the same cost and ordinary primers. Now that is no longer true. Primers in those strips cost a lot more.
So I've saved all my strips. I've got boxes and boxes of them. Haven't had to load any strips yet but the day will come.
