Otari tape recorders

I recently met someone with two very serious looking studio tape recorders that he'd like some info about and a place to sell 'em. Any one heard of Otari or a place that might be interested in 'em.
There is a magazine (also available online) called Pro Audio Marketplace, which contains nothing but classified ads for professional equipment. There are also some used equipment dealers which specialize in recorders. Talk to Audio Village in Palm Springs, CA.
