Could one use pic's as a controller for making flashram strage cards?
     Just thought I could meke homemade ones instead of paying $2100 for
     Verbatim 80MB flashram cards.
            :
     Another question is what difficulties arise in making such cards or
     what makes them so expensive to manufacture?

Have you priced flash memory CHIPS?  They go for around $15-30 per MByte,
which means your 80M card has as much as $2400 worth of "just chips" in it.
You can't get ANY semiconductor memory for $300/200MB - even RAM at it's
currently deflated price is $10/Mbyte...
