Reply to question about rane sl4 with traktor pro

Searched the community but couldn't find my answer, found this tread.

I've been tempted (by myself) to buy a sound-card as backup for traktor, but for a while i'm believeing about serato ( i would like to learn to use serato as well). I understand the sl4 will work with traktor pro 2, of course i understand it will not work with the scratch version.

But how do i have to compare the sl4 and the possibilities traktor pro 2 has to offer. can i use traktor pro 2 with all the options it has to offer. if i use for example two x1 and a mixer

I would believe so, but maybe someone can give me some confidence boost, i can get the sl4 for retail price so i believe it will come closer to the audio 10 with scratch pro upgrade.

And together with a denon 1600 mixer (also for retail price) (Traktor scratch certified) i'm still better off in pricing then a pioneer djm 900 mixer (I know, but that's what I'm believeing about lately)
