I loved G70 and also E80, but just too heavy to carry around every night. I also liked BK7, but too many peripherals required. BK9 was nice, but same issues--no vocal processing or harmonizer, no decent display features, etc.
I probably used the E50 longer than anything else. It was a great MOL arranger in its time.
The kids will love it. If not, you will love it.
