OK, I've looked around some more and this is what I've concluded:
The Smurf was the first version of the 2008 Blue Sub, it's still around.
Somewhere along the line another version of the 2008 Blue Sub came out - with a darker, more royal blue dial/bezel. This is the version I want.
The lighting used by dealers when taking photos varies SO much that you think you are looking at different versions of the Blue Sub, but in fact it's the exact same watch.
I think I'
ll go with Joshua's budget version, and the QC photos will show me the true color of the blue dial/bezel.
Thanks much for your input.
