Whether it's junk or not is only a matter of opinion. While it may not be the latest and greatest, I have a couple of hundred dives on my Dacor Extreme regulator (1995) with absolutely no problems. From local cold water dives (NY), to quarries to the Caribbean and at a wide variety of depths it has always been easy breathing with no freeflows. I get it serviced regularly as I would with any reg. My Dacor BC was replaced two years ago with a Zeagle Ranger and although I'm looking at a new Scubapro Mk25/S600 regulator, my Dacor equipment worked well with no complaints and I would say I was completely satisfied.. (And, yes, I did get a free dive vacation when I bought the equipment many moons ago).
In retrospect, and if possible, your best bet is probably to "test dive" gear your interested in to make sure it meets your expectations and needs. Special applications (cave, tech, etc.) of course will require specialty equipment.
