12um pore size 12well transwell plates

Dear Flowers,
 
Although this question is not flow-related, maybe someone from this list
can help.
 
One of our PhD students is using Corning /Costar 12 well transwell
plates with a pore size of 12um. 
Last week the company told her that they have a problem with the
manufacturing of these plates and that they will not be produced before
mid 2008! 
(As you can imagine this delay is not compatible with doing a PhD )
She is therefore urgently looking for an alternative. 
 
If anyone knows of a company that sells these plates, please let me
know.
 
Thanks in advance,
 
Floris
