Reply to Question about soundcards?

I've been looking into this two soundcards on ebay and they are both of course made by the same manufacturer and I believe both look identical. However, when i read the description it looks as if one will work for the VCI 100 and the other one just serves a different purpose.

Technically, are the both compatible with the VCI 100 as far as using of course for the speaker, microfone and headphone connection that I need or do or only one does what i need?

Here are the links...

(The more expensive option that I need and the one that looks as if this is the right one)

Also, I ran into this one the Behringer U Control UCA202 USB Audio Interface
much cheaper option, but I want to see if this one will be compatible with the VCI 100.

I'm just starting out as a DJ and yes, I could invest some money, but I really want to see where I want to take this. Whether I stay in the room or take it to the next level (If I do of course my set up will need some serious dough) but in the meantime, I just need something cheap that will get the job done and will work with what I got. Thanks for any info.
