There seems to be a lot of these incredible auctions on eBay. Noticed an old Kodak/Nikon DCS 200 (1.5 mp) with a starting price of $1799!
These typically go for around $250 and that only because of the Nikon 8008S body.
I was thinking of buying a big CF card for my D70 (I´ve got 256 and 512) but the price is just too high, so I bought an Ipod with a memorycard reader, it also plays music and works as a hard drive.
My Ipod has a capacity of 40 gigabyte and can store more photos than I can take in a month.
But the really good thing is now I can shoot like a maniac and also store in NEF.
I believe there are people who post "spoof" auctions on eBay for the entertainment of their friends. About a year ago there was a thread about someone selling a computer which had been tossed out a fifth-story window or something.
