My other synth is an EMU Vintage Keys. The AN1X covers the analog
quite nicely and the EMU covers the cheesy organ and the mellotron
sounds. Some people don't like the sound of the older EMU modules,
but when you play it through a 1968 Fender Bassman amp it sounds
quite nice.
Also, a melodica, a weird little harmonica keyboard available at
melodica.com is a nice cheap, portable keyboard with a cool organic
sound.
