I hear you. I have a marimba sitting in my basement that exceeds the value of 5 or 6 of my basses put together. Now that my kid is in college, it mainly gets used as a countertop for my other junk. The investment did pay off -- my kid remained committed to music thru high school, and is now on the drumline of a Big10 marching band (and loving it). Kudos to you for supporting your kids' music. Believe me...it'll be WAY worth it to you in the long run.
