BMW Repair: Z-3 Control Arm replacement, ball joints, bmw dealer

Question
I have a 2000 2.3 Z-3 that needs front ball joints and bushings.  Is it worthwhile to replace the complete control arms for an additional +/- $300 in parts costs, or can I go with just the ball joints and bushings?  My intent is to use OEM Lemforder joints and OEM Sachs bushings.

Answer
Go with the complete cotnrols arms. Much, much, much easier.

Prices seem high.  Check on-line places.
