Sam, someone offering $1,000 for that Cary CDP is either wildly optimistic or a creep. Because I can't tell which, I might reply with a simple "Thanks for your offer, but no."
Because I've been thinking about a Cary 303/300 for a few months, I've watched A'gon pretty closely for that player (including your listing) and other players in the price range. Few or perhaps even none have moved when listed at $2,000. Several have been slow to move (couple of weeks, min.) when listed between $1,750 and $1,850 and a couple of those included high quality NOS tubes.
Even a Cary 306 listed at $3,000 took three weeks to sell and that is a great deal. I'm not sure if it is the economy, increased interest in PC-based audio or universal players, but nice redbook players have been very slow to move.
