Need some help in buying studio monitors.
Hey, im plannin to buy the KRK rokit 8
Just help me with these few queries please. 
Firstly on the site it shows that the G3 version is out but all the links they have provided show only the G2 model. So i don’t know where can i get the G3 one?! 
Also what’s the up-gradation between g2 and g3??
Some sites show that its of $250 while some show me only $190. Why is that so? Is there something missing in the cheaper one?Also these sites sell it as each piece so is it fine if i buy 2 pieces and then hook them up? Will there be something wrong if i do that?
I have a NI Audio2 dj. Can u tellme how to set the speakers up with that and if the audio2 will work perfectly for this?
If i want a balanced signal how do i connect them to my laptop? btw do i even really need a balanced signal?(producing in a room) Like will it even matter?
Lastly some site are offering to provide me with a pair or R8’s along with 2 mic’s and isolation pads for $500 are these sites trust worth? heres the link: http://bit.ly/15gsqpB
Please help asap thank you.
