Cheap, works well, lasts a long time.


What you get are a few untested, packaged chips.  The way this works is 
they do
a wafer with a few hundred (or thousand) projects on it and everyone 
shares the
cost. You pay for silicon (cheap,) Packaging (not as cheap,) and your share of
the NRE for the combined mask (big cost, but shared by many.)

Engineering is like having an 8 A.M. class and a late afternoon lab...
      ...every day for the rest of your life.
