Prius Shaking in the Morning? Will Plugs, Coils or EGR Fix It? Probably Not. Coolant loss is not obvious until it gets bad.
I wish they'd back off on the infomercials, put up the how-to videos that they took down. I have them downloaded, but.... I really don't think it'd hurt their business; it is a lot of tricky work, and I'd suspect not many of their potential customers would go the DIY route after watching them. And it'd be a feather in their cap, and maybe they need a few.
They still have a good head gasket video from March, with close shots, good editing and narration. The comments are monitored and responded to by GMasters as recently as yesterday. They also have a video on replacing the engine and another on setting the timing.
