I've got one. It's a love hate relationship. Once you run it a few times you'll be right. Mine is still as I got it from the factory yrs ago, APS strips. Yes they still have parts available, although I don't think RCBS still makes the die plates. There's a seller on ebay has some nice blue anodized ones for 55 or so.
It is a good unit, I've probably loaded 15k rounds or more on mine. Pay attention to the linkage fasteners on the powder measure while you use it, and check their tightness at the beginning of each session.
If you are using the APS feeder, watch your indexing on the shell plate and make sure you hear the strip "click" before pushing the ram forward to seat your primer. Failure to do so will damage the strip.
Also be advised the unit may not completely index the shell plate, you'll have to give it that last extra push forward. That's a good thing tho, as if you're loading short cases, the abrupt stop on the detention ball with make the powder fly out the cases.
I can honestly say I've about see it all with a Pro 2K, it does what I need it to do so I don't bother getting a blue one.
