Sorry for the late addition to the thread. 
There were a couple things I agree with Misha-
san.  One, that, if I dont have all the sequence, 
I would usually sell it.  Good example of a cel I 
recently acquired, but having thoughts of 
selling, since there was another same exact cut 
that someone else won.  Probably not the same 
reason has her, but, the idea of getting it all 
is the nice part about a sequence, can't get 
enough with just one...hehe 

Second, just wanted to add this to the example, 
that junk cels (body parts) makes a good 
sequence. Looking at your cels in action is 
nice.  Complete 19 cel sequence cut from one of 
the Burn Up W Opening (I think, havent confirmed 
yet, labeled on cel) of Rio.
