Vic just to throw a wee spanner in the works....the new generation PCs do not have firewire....it is all but obsolete and being phased out.....most new Pcs only have USB. So you may find that a firewrie interface in a couple of years will not be compatable with a new PC.....I would go with a USB interface. Presonus do a range that would also suit your needs...plus there are other makes that will also do the job....Beheringer, Focusrite, Alesis, Tascam, Lexicon and M audio...to name just a few.
