Reply to DJ Soundcards

Ive got a question about 4-deck DJ soundcards to connect a analog mixer (like Xone 42) to Traktor.
Is there any other soundcard except the A10, with almost same quality? Or even better/worse?
I know there is this Motu ultralite soundcard - which costs about same price as A10 but should offer a higher soundquality and even more connectivity (though through 6.4mm (1/4") jacks).

Are there any other good cards? If yes - which/how much/how good/worth it?/better than A10/worse?


Additional hint: I only need to connect my pc via usb to a 4 channel mixer...thats it. no need for a mic IN etc.
