I didn't make any claim as to the ebay units, and don't know anything 
about them except what is stated by the seller.  I just said that 
their claims were "in the ballpark" of what I considered standards of 
interest to this group.  That was in relation to the OP's proposal of 
a 0.1% standard (1000 ppm) -- a standard could miss what I defined as 
interesting by quite a lot and still be in the ballpark compared to 1000 ppm.

Best regards,
