I'll second all the good comments about G1000s. Best plastic action on the planet! Very reliable (gigged mine 24/7 for eight years!) and a CHORD SEQUENCER..... the best practice and songwriting tool you could ask for.
I have a friend with a G1000 AND a G70, and he still uses the G1000 for all arranging functions because of the chord sequencer.....!
