Lift kit suggestions

I'm not a mechanical guru so please excuse me for not having any wits about me in regards to suspension components.

I'm eying up a couple 3" lift kits at the moment..
4X4Parts'
http://www.4x4parts.com/public_html/shop...a950a26fb884bb5
FOR $410

and Calmini's
http://www.purenissan.com/3_lift.htm
FOR $980

I noticed that Calmini's kit provides you with struts, aside from that why would I choose one kit over the other?

Thanks!

Calmini's lift you won't have any issues trying to get your front end aligned correctly!

You also get new torsion bars and AAL's with the Calmini kit. There are reasons the AC kit is cheap!

I did notice the torsion bars as well, but what are AAL's?

Add-A-Leaf, got it.

Thanks for the help!!
