Value
I had a new beginning student last night and she asked how much a harmonica was. I said $65 (I sell the Hohner Crossover), and they're the best pro-level harps on the market. She was impressed that you could get a professional quality instrument for that cheap. I agreed!
We often criticize harmonica companies for the cost of our instrument(s), but we forget to step back and see their true value. If you have the opportunity to visit a harmonica factory, you'll see the amazing amount of hand labor that goes into each harmonica and would forever be an advocate of what a value they are, even for our most expensive models. So, don't get caught up in the fact that we need to have multiple keys... of which I know makes our end cost go way up... but EACH harmonica is a valuable instrument in itself.
Moral of the story, quit bitchin' about the cost of harps and play the dang things already! ;-)
