On the other hand, I had a reasonably priced - not cheap, not over-the-top
one and it was as accurate as our lab methods.  This leads me to guess
there's not so much a problem with the technology, as a problem with people
selling cheaply made crap, where some work, some not so much...

I had one of those cheap pH meters, too.  I scrubbed it with steel wool 
and stuck it in my soil.  It read 7.0.  I scrubbed it some more and wet 
down the soil more.  It read 7.0.  I brought it inside and filled a 
glass with one part vinegar and four parts water.  It read 7.0.  So I 
threw it away.
