Back a little over 20 years ago, I bought a Dillon RL-550 press. Came with one toolhead, one powder measure, and one set of .45 ACP dies. Over the years, I've probably loaded 30K+ rounds on it, mostly .45 ACP and .30-06. Never a headache, never a bobble. Over the years, I've acquired a couple of extra toolheads, and branched out into reloading .38 Spec./.357 Mag, .45 Colt, .308 Win, and 7mm-08 Rem., but for some reason, I've only used the one powder measure. It adjusted easily, maintained excellent accuracy, and never gave a moment's trouble.
Last night, while setting up to load some 7mm-08, the powder measure hung up, and while trying to "encourage" it, broke a little tiny plastic piece. (Please bear in mind, that this piece, like the rest of the measure, was in original, as-purchased, condition, and was 20 years old.) Breaking that piece turned my powder measure into an awkward paper-weight, and left my reloading venture dead-in-the-water.
Called Dillon this morning, explained about the broken piece (it's called a "bell-crank cube") and they have two of them enroute right now. Total cost: Nothing.
Dillon stuff may be a little more expensive, but their customer service is the best in the world!!
