I was thinking of selling my old digital camera on ebay

And by old I mean 1975.  No really.  It is a Kodak.  A little bulky by today's standards, but you can save money on SD cards because it records to a cassette.  Then all you have to do is run your data through a processor the size of a suitcase so the signal gets converted from 100 lines to 400 so it can be broadcast to a  TV tuner on a standard NTSC video signal and voila, "Film-less Photography."  Who wouldn't want that (except the film manufacturing company that just went bankrupt who decided it would be bad for business plus nobody would ever want to view photos on a screen)?
