if I had enough money I would buy all three. 
since B and C sound like they are 
RELATIVELY affordable.

if B and C arent TOTALLY kick ass though, if 
they arent REALLY wish list cels, then I would 
suggest not getting either and holding out 
(and saving money) for the next tim you see a 
cel as cool as cel A.

I often would get trapped by the idea of "wow 
that's a kick butt cel" but it wasnt one of my 
wishlist cels, and eventually one of them 
would show up and I wouldnt have the money.

I think cel collecting now is a waiting and 
saving game... and choosing what is worth it 
and what isnt...

and then biding your time.
