For what it's worth, he sent me one of the early pre-production units - I use it every day and it works with zero issues hooked up to my Replicape+BBB 3d printer. I use the on-board power setup (proper USB standard at 0.5A), and it works flawlessly with a USB wifi dongle and webcam connected. I've had no brownout or power issues with it, and I have been very pleased with it.
What's the saying? "The best products just work and you don't notice them because they're never a problem"? That pretty much sums up my experience. It's near perfect - my unit was mildly fussy about how I installed it because of the cape's power pins etc possibly causing a short so I needed to tape and hot-glue some metallic surfaces to avoid magic smoke escaping, but that was a pre-production unit :) As far as I could tell from my last conversation with Steven, BOM cost is dependent on the size of the production run - unit price goes down the more you make...
