check this site out.. tells you what there is..
http://www.dolphinmusic.co.uk/?page=shop/soundcard_selector&advanced=1helps you choose..
and as the motu 828 mk2 setup.. got it myself and very happy about it.. got mine for about 560 euros, but it was secondhand..
m-audio is a nice choice as well, worked in some project with their gear.. never any problems..
if you want to spend big, try RMEs audio interfaces they are the bomb.. but very expensive..
presonus looks nice but dont know about their quality ad/da s
if i had to choose between m-audio or presonus i'd choose m-audio. their gear is rock solid, for their pricerange..
terratec, nice cards for the beginners.. i would classify it as hi end consumer instead of professional gear..
good luck.
