Welcome to the site.
The difference between harps is the reason why, if you carry on playing, you will end up with quite the collection!
I settled on the marine band deluxe a couple of years ago as I figured the marine band is the most widely available harp, so if I lose one or break one when I’m away I can always get another!
They also play beautifully imo.
I still have a soft spot of the suzuki bluesmaster though.
Have fun playing.
