The prices went up a considerable amount a few 
years back, when the HK DVDs first came out ^^ 
Still, you can find pretty fair prices on the 
Japanese sites...I picked up a decent Hiei for 
$80 around X-mas time. For face closeups, though, 
expect closer to $150. 

As for Kurama...yikes. You're in triple digits 
for sure. I would say $150-$200. 

good luck searching!!!
