Late-period NCC doesn't look great. But I've been a buyer of these services for the past 5 years (a seller, of course, for the 15 years leading up to that) and rates have not gone down; I was shocked at how much we ended up spending compared to what we would have billed out on comparable projects at Matasano.

I don't know enough about the low-end market to rebut you there (though: I saw what my muni paid for a bargain-basement assessment and was not OK with it), but the high end of the market definitely has not been slaughtered, and I definitely think that is coming.
