I got a nice surprise today (surprise because I had forgotten about the upgrades that were to be sent to field testers of the PCS). The package included a new control box (supposedly more robust with magnetic contacts), new riving knife, new safety guard with dust collection port, improved dust port (4"), new manual, and a new blade gift for being a field tester. SawStop continues to be a class act and their attention to detail, manuals, follow through, and overall quality are among the best in my opinion. Supposedly this package brings the early field test models up to the latest production level. I do not have a lot of time on my PCS as I do most of my shop work in the winter but so far the saw has met or exceeded my expectations. Ed
