The new Quantum Gardian line should work fine - but you will need to use
Samba HEAD on the PDC.  (No prizes for guessing what's inside ;-).

We are aware of the issues with NetApp - and need to determine how we
differ from Win2k.  Unfortunetly due to the relitive market size, NetApp
is unable to put much time into this from their end, but have given us
some assistance.

This is the basic argument over 'why pay this much for a NAS'.  Most of
the things that you can do with a NAS box you can do anyway - it just
depends on how much time you want to spend setting it up etc.
