Sorry, a 500 can't be considered at all. That would really be a step back!
I should really have been more clear...I would like to trade this for a Sony Prs-505
or technically similar reader. If the other reader is not a Sony, it would have to
have the same screen specs as the 505 and internals. The 700 is in perfect new like condition so I would appreciate some attempt to equal out the value as well.
A nice cover or whatever would be really cool. I hope that's not asking too much

If anyone has any criticisms or whatnot, let me know! Oh...the reason for wanting a trade
is that the the better contrast of the 505 proves to be more valuable to me than the touch screen and it's features and the built in lighting
All my best
Ron
