re interface.
zzounds.com has a slew of interfaces which you can sort from low price to high price.
one particular brand that i keep on hearing is good due to convertor quality
in the ADA stages is echo for the price. but caveat emptor as always.
run your own tests n make sure you can return any device if it dont play nice with
your puter.
