Best place to buy harps in this universe:
Rockin' Rons Music
I have a few marine bands, but they need a bit of work---usually a little and a lot does wonders.
Stock out of the box I would suggest the lower end Suzuki or Seydels for beginners. I do have, and love, Hohner Golden Melodies although the all have custom combs and have been gapped and tuned. You might try Blue Moon Harmonicas----Tom sometimes has mildly massaged harps when he has time to make them and they a great deal.
My favorite is the Seydel 1847. Super out of the box..but you want to make sure you really want a harp before you invest in one of those puppies. I only have two, in my favorite keys.
