Eww...what a hard thing to decide..
I guess it would have to be my Sh'ten cel as 
the ancient from Samurai Troopers.  I've been 
looing for one of him for a long time.  The one's 
I've seen before were way too expensive on eBay 
and I was beginning to think I'd never find one I 
could afford.  What's even more strange is I have 
another one on the way ;)
