After searching there are various posts about complaints etc... about these but I'd like to get a thread about em all.

Trying to find out what the best way to go on these....

First up there is the type that replaces where it mounts to the tower.
-The only time ive seen these in person they didnt fit correctly.
-normally the least expensive

Second is the whole upper control arm with a moveable ball joint held in place by 4 bolts.
-my concern here is the ball joint coming loose from the screws backing out.
-normally middle priced

Third is the upper ball joint on a cam type mounting.
-concern about it not staying locked in where you want it.
-normally highest priced

questions...opinions...ideas?
