Q on Speedplay cleats

I think I've tracked down the source of clicking when I ride--my
Speedplay X cleats.  When it's not quite so hot I'm going to see
if tightening the tension screws helps (the C-rings have quite a
lot of play as currently set).  Further, I get the clicking on
both my single Ritchey and my tandem--two different sets of
pedals.

In any case, I'm thinking to get a new pair of cleats.  Even if
the adjustment resolves the clicking, it wouldn't be bad to have a
backup.  I'm wondering why the huge disparity in pricing (~10X). 
What looks to be official is ~$200...

...whereas another source has them for $23...

Based on the language of the description, I'm guessing these
latter cleats are of Chinese origin.  And I did notice the title
says cleat covers, but the pictures (and description) all show
cleats.  Also, this may be what I bought last time.

Any tips?
