We recently traveled to Europe and we lost our camera Cannon SD500 or 550 (not sure) while in London between Covent Gardens and Trafalgar Square.  I am absolutely devistated by the loss.  My fiance proposed to me in Prague and I had pictures of this on my camera (also pics of London, Paris, Cardiff, and Wales).  The camera was in a black case with a 2GB memory card.  The front pouch of the case also contained an additional 2 GB memory card.  Full memory card is the most important to me!!  Reward for return!!
