DCA instructors did get a slight raise recently.
Also, the hiring after initial CFI has gone away as they're starting to get enough SR-20 instructors in the system to scrape by. Instructors, however, are very much overloaded at present. On the bright side, they're building hours quickly.
At the moment, they're "encouraging" students in the older equipment to transition to the SR-20 as soon as possible but that, of course, comes with a transition course and associated bill.
Overall, the cost of DCA has gone up significantly with the fleet change. The training is good, though it may be a few months before things get ironed out with the new curriculum and aircraft. Unless you have an endless font of money of draw upon, I'd think very hard before choosing DCA for your flight training.
