I just received my Walkman from the Ebay auction that I won a few weeks back. I believe it was an excellent price. The seller has had excellent communication. It came from the UK and came with extras(no adapter):

The first unit that I won (and since returned for a full refund) was the "D6"-not the "D6C". It turned out to be crap, featuring things like a big crack in the case and a faulty tape counter. The seller turned out to be a horrible seller with a really bad attitude:

So far, everything works and I'm jazzed!

i feel for you man, defanately there are some crazy and horrible sellers out there,
i had my share of them, glad you got your money back tho.

Yeah, I'm thankful for Ebay buyer protection. It seems as if the economy has brought out the cockroaches who attempt to turn Ebay into a breeding ground of fraud and deception. I'm still blown away at this mint D6C and the included extras...

I wanted to add here that I checked out all functions and this thing works absolutely perfectly. I am completely and utterly astounded at this thing and it is by far my most favorite Walkman. The headphones and mic work fine and everything. It's brand new. the original owner said he only used it a handful of times and then left it in his "cupboard". Original receipt, instructions, box, everything.(no adapter) The carrying case and unit and everything is immaculate. I paid a total of $292 including shipping and I would hope to double my money if I sold it today. I don't know for sure if $585 would be reasonable, but I think it really might. Justice for me? My luck has certainly changed in 2011.
