First of all, I'm not sure if i'm posting this in the right section, if I'm not please forgive me, I'm a newbie.
 
I'm trying to look for an external sound card that could act like an amp at the same time, I'll mostly be using it for my computer and I'm looking for something around the 50-60$ mark to go with my DJ1 Pros. 
 
Not sure if this is relevant but I mostly listen to techno, dubsteb, pop, hip hop and classical
 
Thanks in advance

This one used, I suppose, but you should save up more in my opinion.

You should probably increase your budget. External interfaces aren't really reliable until $150+. I would suggest http://www.bhphotovideo.com/c/product/393375-REG/M_Audio_9900_51076_00_Fast_Track_Pro_USB.html
 
My brother uses it and hasn't told me of any issues. I think it's a good entry-level interface.

the older version of the fastrack has the same specs, and you can get it for about 99 dollars as part of one of the maudio essentials kits. Its still above budget for what the original poster has in mind tho
