Hey reading all this about book readers etc got me thinking. I have the =
original APH Bookport and an external DoubleTalk LT. I do not need =
either and would like to get a couple bucks for these things and find =
them a new home. So, is there somewhere one could post stuff like this =
without having to join another list?
THanks,
