If he's your boss, I'd advise you to let him set the price (and then pay it). The job market's pretty rough out there!
In good shape it's probably a $20 USD camera. I've used the older Exakta mount Exa - very cute, but very unreliable (unless well-serviced at least). They reflect the QC problems common to much of the Eastern European consumer goods manufacturing of their era. They do have a small following however. Their market was to allow the use of Exakta mount lenses without the expense of a full-featured Exakta body. Of course in Bayonet and M42 there are tons of excellent lenses, east and west production.
