If that is your goal–the harp you want is the one that you love
to play/practice on–whether that harp be old, new, lever, pedal, small, or large. If you don’t love it, it will be that much more challenging to practice. Harps sound different. “Identical” new harps sound different–and they will change further as they age.
You also need to be able to reach all the strings and pedals–AND to be able to move it by yourself. If you are small, or young right now, and can’t move a CG or reach to play it, what you may need in the future is a moot point.
This harp is unlikely to be the last you will ever own because your musical needs and ability will change.
