That's an August 2008 article. I think they are caught up as far as backlog by now, or at least not as far behind. For a long time, you would never, ever see a Ric in a shop anywhere. Now, they are not exactly common, but they are around. Who knows what effect that's going to have on resale value, street prices, etc. I don't know if they will become a fad because people can have them now, or if they will just keep plugging along as a bit of an oddity. Really, how often do you see a Ric on stage? Probably more often than you would guess from how few there were floating around, but they haven't been particularly common.
The article's comments about the new machinery Ric was installing to increase production rates gives some real insight into some of the QC problems people report. It probably took them a little while to figure out how the new machinery actually worked and what the critical factors were. At this point, I would expect the QC to be excellent. In the late zeros? Probably not near as good as they figured out how the laser cutters, UV curing, and metal injection molding equipment really worked and what the limits were.
