m-audio profire 2626
presonus firestorm blah blah
all about the same quality wise...
echo 8 pre looks good and i've used some of their products before....
def a cut above the stuff at the top but u'll pay for it.
recently bought a Steinberg MR816x and returned the 2626 huge improvement in the conversion and pre's but its prolly out of ur budget.
