You did not look hard enough. There are 62 threads on 3 pages of results when I searched "wapi".
Several threads extol the virtue and price of these razors. HERE is one of the first.
There are several more, but that thread should give you a rough idea if you read all of it.
There is also THIS
and THIS
and several more on those 3 pages of results.

I would suggest you also read THIS is you haven't already.

I hope that helps.
