<VV> Quick Steering Arms

[Padgett]

I would appreciate a "quick" education. Know that the fast box is the best 
way to reduce the number of turns for the street but 4X the cost of new 
arms from Clark's. My question is (know to avoid welded arms):
1) Is there more than one product available ?
2) Are some to be avoided ?
3) How do you tell which are good or which are to be avoided ?
4) Is there a difference for autocrossing ?
