Aftermarket vs genuine Lower Control Arms

[Zoran]

I have been told I need to replace my Lower Control Arm rear bushes. After some research, it is apparent that the recommended method is to replace the arms entirely rather than just the bushes. 

Genuine arms are abut $1000 ex (for the pair).

Non-Genuine are about $500 (for the pair).

I could also go down the route of importing the genuine ones from UK / USA etc.

Would love to hear from other owners as to their experiences.

Cheers
