there are surely lots of things out there, i've got the RME fireface800 --- it's not cheap, but for the long run, kind of an industry standard really...at first i bought/used something else, half the price, but i only had problems with performance, drivers, latency ... that was a focusrite saffire pro 26i/o discontinued after two or three years...only good thing about this one is, that the preamps are quite good and i can use it as an 8-channel mic-pre and connect it via adat to the fireface...
i would always recommend RME stuff...
