Photo Frames with "Hard Drive"

[BLUE SKY THINKER]

I've deleted previous post entitled Digital Photo Frames and renamed above, as several people I have spoken to today don't seem to have a clue as to what I'm talking about; maybe likewise here.

The "hard drive" varies, sometimes flash cards in one format or another. Either way, image options vary from static to slide show, with a myriad of time intervals in between.

As previous, just interested to know if anyone has had any experience of these, or more to the point, has come across any reasonably priced examples (pretty astronomical the few I've found so far).
