I know the feeling, I wanted one soooo bad last month and found one on ebay... be patient... there might be one soon!
I was looking for the khaki large paddington hobo from '05, for the longest time and finally, finally, (took about 6 months) someone was selling one that had barely made it out of her closet the whole time she had owned it. It was perfect, mint condition, and I did a BIN immediately...it's gorgeous. So, I believe that you will definitely get the blue, but you have to be "on a mission." GOOD LUCK and if I see one, I will let you know ASAP.
Cristina's is a killer bag as well!
