I've been listening to some old Messiaen recordings, and I've become entranced by the sound of the Ondes Martenot. It seems to allow some of the interaction that string players can feel with their instrument, but with a more accessible keyboard setting. It has an ghost-like, "horror-movie" like sound, and can produce glissandos which send chills down my spine.

Anyway, I was wondering whether anyone knew of a place to purchase this unusual instrument. Due to the lack of music written for it, my preliminary searches didn't reveal any commercial models of the Ondes Martenot. Unfortunately (due to my lack of experience with technology), I am unable to build my own, as I cannot understand most of the directions for how to build one. Thanks for your help!
