Anyone play Harmonica?

I'm just a little curious what you guys think of the many instruments classified as a harmonica. Any favorite tunings? Anyone goof around with chromatic, bass, or chord harmonicas? Anyone here into customizing? I've been building a small collection, myself. Seydel Fanfare Bb (tremolo) Seydel Blues Favorite low G Seydel 1847 Noble low C Hohner Thunderbird low D Hohner Crossover G Hohner Golden Melody C Suzuki Firebreath low F Suzuki Promaster A Lee Oskar E major I've also got a Seydel Concerto in high G and a Seydel Sampler in C/G in the mail. Any harp love?
