I know that this is a subjective question that only I can answer for myself, but I pose it in regards to current market value in North America.
I've been missing my K-1000 since I sold my old pair last year. Now that I've gotten rid of my entire speaker rig (save the Aleph 30), I'm back to cans for home listening. There is a local bass heavy, in original box, K-1000 that I can get for $1,300 CDN. Is this excessive? I know that the higher serial number models like the one that I had are as low as $1,000.
Keep in mind that I wouldn't have to pay for overnight shipping (instant gratification), Paypal fees, or deal with potential scams.
