Plenty of schools are filling up their slots and becoming very busy... not only DFA.
Almost everyone finishing this year from different schools is getting a job in airlines, I would rather move forward than wait 12 month to start the course.
Aviation is on the good cycle this year. Who knows what will happen in 2019/2020.
Regarding the school I heard good comments too.
Regarding the DA42 is a great aircraft to fly and super easy to learn.
G1000 is a great tool and easy to use, however you need to invest time in order to know every single details/function in order to be ahead of the game. Once you know everything it is super easy.
Suggestions, get iPad applications/simulators, read the G1000 manual and also if you fly a lot while building hours, try the Garmin Pilot application for iPad which it would start showing you the Garmin concept/way so you get more familiar with "their language".
Flying any aircraft with G430/530 or even G5 plus iPad Garmin Pilot will be a good way to practice. Learn every knob, function and button, the G1000 is similar concept.
