Anyone know/use River Cable or Lat International?

I'm wondering if anyone experimented with either one of
these companies?

According to stereophile the rivercable digiflex is the best digital cable at ANY price and it's only $42/1 meter.

This one is a bit more than river cable but also fairly reasonable by comparison.
