Want to start playing the harp, and i don't know which one to get can get all so any suggestion will help txs.

This thread should be in the "Harmonica Chat" section.
Ask the question in that section and tell us what kind of music you want to play. You're sure to get several responses.

I posted an answer to your post in the requests section on the tremolo, so if you read that, then go to the harmonica chat section and read the diatonic vs chromatic post, this will give you some idea of the three, and what you may want to do. If that doesn't, then do as gene says and you will get additional help.
