That's really the best place to get them.

I use Itoya presentation books (11x14 and 14x17)
as celbooks.  The only art supply store in 
Columbus that I've found carries them is Utrecht, 
but they're very nicely priced.  (11x14 books are 
usually $9.98 vs the $17.50-21.50 charged for the 
same item at a 'celshop')

If you don't have one close to you, you can mail 
order them from Utrecht's website: www.utrecht.com.

Search for Itoya and they'll be the first 5 items 
at the top of the list.

Hope this helps!
