everybody likes a good bargain. The problem is all of the labor/tools/time required for front suspension/steering R&R. It's hard to say how long cheap Chinese grade parts will hold-up and nobody wants to turn around and replace a lower ball joint again after 6 months. At least with the more expensive, name brand parts you have confidence that it will last a long time, not to mention the consumer reviews and positive feedback that goes with it. I haven't always had the best of luck with even the most expensive ball joints in stock; after having to rent & borrow certain tools over & over, then spend hours upon hours replacing said parts when I would rather be doing anything else I just assume go for the best quality possible in these instances. But good luck and keep us in the loop on longevity issues.
