EXS 24 Logic Sampler Users Group

Hallo all, 
I am currently shopping for audio I/O hardware for a Mac G-3 B&W 350, ext.
Maxtor 40 Gig Firewire HD Logic 4.7 Platinum system. This system will be
upgraded to dual G4/Logic 5/6-EXS24, Atmosphere, UAD-1, OSX system, later in
the year. 
I am currently debating the MOTU 828 and the RME Hammerfall . I was
wondering if I could please ask for advice pertaining to issues such as
latency, quality of sound (DA), reliability, performance (on present G3 and
future G4), and anything else any cares to comment on.
I cannot seem to get many comments on this subject on the Logic list so am
hoping this is the correct place to ask. If appropriate please email me
privately.

Thank You,
Vincent
