Get an ARB.  
BTW, the 2006 Xtrerra is a fully boxed frame and Sandy's is a Ladder frame and not unibody.   The ARB's are designed to shore up the frame in front of the front crossmember.   An ARB is bulletproof.  I believe they are around $800 for an Xterra.   A few of the guys in the club have them, I wish they made em for the CJ7, I'd buy one.
