Hmm, I hadn't realized that--I had mistakenly assumed that the poppet feature 
started with the models having individual color cartridges.

Thanks for mentioning these; that makes the MIS web site statement (about no 
poppet valves in "clone cartridges") rather out-of-date. I guess the speculation might 
be that these aren't really "clone" cartridges--perhaps they fell off the back of a 
(Chinese) truck?
