I'd say check competed auctions on Ebay. If you can wait I'd avoid selling now. I've noticed some very low prices on large format equipment. I won't tell you what I paid for my Maximar 9x12's but it was a lot less then $200. And these included filmholders with film inserts. Some of the holders were like new. Mine were good Ebay deals that are not everyday prices. I think you will be lucky to get $100 in todays market.
