There's two way to view the value of parts. First, you can look at the potential savings and consider the potential risk of premature failure for a potentially lesser part. Second, you can think about if you would be kicking yourself for "saving" $x if you end up doing a trail repair.
For example, saving $50 might seem like a great deal, you might quickly hand someone $50 or more if you could magically fix a trail break.
I am not intending to suggest that the Precision joints are inferior because I have no experience with them. Just sharing a way to evaluate things in general.
