For various reasons I have traded in my DSP-6K's for some other equipment. This is not an ad but I see that the place where I did the deal are asking abt USD 5600 for them.

They are abt 20 months old. I'm asking out of curiosity because I have not seen 2nd hand 6K's on the market before so I wonder whether the price is reasonable? It sounds cheap to me, I think I bought them for more than 3 times that amount?

Guidance please! I can use it in forthcoming negotiations! I'm also thinking of trading in my 861 but the prices here seems to low so I might just keep it!
