Simply ask ;)

Seriously, I think that this kind of things are not too much money, like 
for example the ADSP-BF537 Stamp from Analog Devices 
http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=ADZS-BF537-STAMP-ND

We are not building this one in large quantities, but we've used it as 
an starting point for several projects (see the space projects section 
on my web... all of them have one or more inside ;) )

Do you think that the STAMP from ADI is too expensive? :)

Regards,

Javier
