Hi:  I use a scarlett 2i2 (first gen) on my office computer (my studio DAW uses a MOTU 828mk2 hybrid).  The  scarlett 2i2 just died on my office computer.  
I occasionally will record a guitar into it and use S-Gear.  So I do need to make sure the latency is okay, not stellar, but as good as the Scarlett 2i2 was.
 
What would be a good low cost replacement?  
Another Scarlett 2i2
Presonus AudioBox USB96
Mackie Onyx Blackjack
Steinberg UR 12
 
Thanks

My choice of the ones mentioned would be a new 2i2 second generation.  The second generation are "new improved".
I'm not a Presonus fan  (every new one I've tried has had a hardware problem).  I'm not a Steinberg fan either because of the required e license software that is required to activate the device (I had a UR44).
