Donny, you are amazing and invaluable, thanks for all your referencing!

ThirdEyeVision, unfortunately, $100 is a tight budget. Do you want to use arranger functions? That was not clear to me. If so, maybe you could also check pawn shops or used-equipment stores. Here in my hometown I have a great dealer who might have something you're looking for, so maybe the same is true for your area.

Good luck.
