Ezy;
Sorry, I don't remember if I replied to your thread asking opinions on what to buy or not. But, I'm another 20 year or so vet of the 550B & I'll recommend it to anybody.
Glad you're happy with it, but honestly that's sort of a 'gimmie' with Dillon. Not to say that there aren't a few out there who revel in sour grapes, but they are in the exceedingly small minority.
If there's anything you want to know about your machine, problems, procedures, or suggestions, the first place to go is Dillon's help line. They truly enjoy helping folks out. But you could kinda keep us in mind here at THR too.
