Reply to ESI Maya 44?

I am reading via Googling nothing but strong reviews for this card and it's price.
Things that look appealing are:

4 ms latency / 2 stereo ins / 2 stereo outs (rca)
separate amplified headphone (mini ok for me)
light and compact, bus powered.
-10dBV input / output level (unbalanced)
The NI audio 4 has Four 9.7 dBu outputs (RCA).. so Maybe NI Audio is louder?
light weight and compact,great for travelling.
100.00 USD

Things I do not like:

looks kinda amateur..but does it really matter??..Say it was in a different box and nobody knew
what I was using..
-plastic case could break over time..



How does it really compare with a NI Audio 4? I do not need the phono preamps
or extra stuff the NI A 4dj offers.. I need good, clear sound and loud enough to pump a crowd.

Any real dj feedback ??
