I've got a huge achika cel on auction, if your interested here's the link
to it: http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=361407088
If that doesn't work just lookup item#361407088 in the search field.
The cel itself is about the size of 4 normal production cels placed
next to each other (2 high by 2 wide).  If you have any questions
please email me.
