Mr. Willis, did you get an answer to your Tokyo soil sample analysis 

The reason I ask is that I also want to play with mca's again as a hobby 
myself.  It has been many years since I did that professionally and I'd 
like to take it up again.  So far, I have no equipment, no sources, and 
no samples.  :) :)  I hear all these tales of low cost equipment but I 
can't find any via web searches!
