My daughter has become quite an impressive mallet artists and I'm considering purchasing a set of vibes. She's past the beginner stage, so graduated bars are a must. When I first entered the high school band room, I was shocked to see a long line of four octave Yamaha vibraphones and a whole bunch of high end marimbas. By my quick estimate, I think they must have at least $100,000 worth of mallet instruments. This all feels to me like getting a new Cadillac before taking driver's training! I bring this up because I'd like to get a high quality instrument, something that will provide years of enjoyment. Looking around, I am quite surprised that the lowest priced graduated bar vibe is over $3200, plus shipping. Used may be the way to go. Would appreciate any thoughts, since most of the used items I see are too far for a 'test drive'.
