If they're buying PPS is rising. The confirmation from 14 PHD's of a productive/cost-effective system certainly says something about what we've got. Not only is it a commercial system (because it's being sold), but apparently it's a pretty good one.
Certainly they had other options???
(If yes, good for us. If no, REALLY good for us.)
