I was on the Clist today looking at the local adds for the heck of it. The add I chased down said Burmese Ball Python $225, no pics. Of coarse it turned out to be a normal 3 y/o bp, still on mice, pieces of shed strewn around the the the tank (included in asking price). Really it was not in too bad of shape so it didn't trigger my impulse/instinct to rescue it.
Good luck with your new acquire.
