At current prices, you'd be fortunate to be able 
to pick up an "amazing" OVA cel of Tsunami or 
Washu for $150.00. A good cel mebbe......but 
don't bank on a portrait shot from a key 
scene.... 

I've been looking for those two characters for a 
long time too. Mind you the last few times 
something nice came round I've been distracted by 
cels of Ryoko my favourite character!

Anime Taro still has opening cels of Sasami for 
sale at around $80.00-$120.00 

Good luck!
