I saw three vehicle cels (helicopter, truck, etc.) 
and a bunch of cels of Spike in a cel of some 
sort.  Some were close-ups, and some were full 
shots of the cel.  Most cels were $80 or less.  
No backgrounds.  One standout was a great cockpit 
shot of Faye (in her Redtail?).  It was the only 
pricey one that I saw. 

Hope that helps.
