I bought a chromatic but could never get the hang of it. Have you tried a diatonic? I use a selection of these, all Hohner (the best!) and the sound is really strong - they are especially useful if you play the guitar at the same time and use the old neck brace for the harmonica as they sound ok in 'hands-free' mode. By the way, I couldn't contemplate a second-hand model when I look at what comes out of mine at the end of a session!!!
