Generally waaay overpriced to get trained by underpaid entry-level CFI's. They basicaly specialize in separating rich middle-aged guys from their money. These guys assume that if it costs more, it must be better.

Also a lot of variability between locations, it all depends on the local chief pilot.

The 30-day CFI program is usually a good deal, that's the only thing I'd recommend. But you won't get the ratings in 30 days...you'll need study/practice time after the scheduled training, plus scheduling delays for examiners. I'd plan on 4-6 weeks after the 30 day academy ends (AF won't tell you this up front).
