I got into handloading some time around 1994. I had the great fortune to find a used Dillon RL550B that a guy was selling to help fund his upgrade to a 650.
It is the only press I have ever owned and I'm not looking for anything else. The Dillon does the things a single stage press can do, as well as priming and charging. I can crank out hunting/ball-equivalent ammo in full progressive mode, and for match loading, the only step I add is to confirm/adjust individual powder charges.
It is the singular best marksmanship decision I ever made, and the entire setup, including scale and dial calipers cost me $250 back then. For five years it served as the team press for a handgun, and later, handgun and rifle shooting team (Marine Corps League Detachment).
It was replaced with a 650 when I moved to upstate NY and took my press with me. The team likes the 650 for handgun ammo, but misses the RL550B for their rifle ammo.
Nowadays, prices seem higher, but it's not just the press you're paying for, it's also the substantial time saving you get for that cold cash of yours. For going on 20 years, that press had paid for itself many times over. I have replaced the scale, added a powder drop tube, and someday I'm gonna buy a dedicated die lock nut wrench, but that's pretty nearly the lot. When you hear the term 'buy once, cry once', this is precisely what they're talking about.
