Speaking from experience in dealing with cheap parts, go with the more
expensive trusted part.  Especially when the work involved to replace the part
is extensive.  

I was burned by "Made In China" wheel bearings that I installed in my Monte
Carlo years ago.  They lasted just a month or so over (1) year before falling
apart.  

After re-replacing them, went with a "Made In USA" Timken bearing, and been
going strong for 3+ years and counting.

Costs about $40 more than made in China garbage, but that is a small price
when you consider it takes hours each time to replace.
