Smoking Box?

I need some advice.   I am originally from SW Louisiana - yes I am indeed a TRUE Cajun as my name indicates....and I grew up around what we call Coonass Microwaves or Cajun Microwaves.  Some of you may know the product as a LA Caja China.  They are basically smoking boxes.  Although this is method of cooking is NOT your typical "smoking that pig on a big black traditional iron behemoth of a smoker"....I recently seen one in action ata BBQ cookoff competition in Raleigh, NC and it really peaked my interest.  What are you guys thoughts on this box?  The pig I had was phenominal coming out of this box....and it cooked it for half the time....and appeared to be less labor instensive.  Downside?  It's a baked product and NOT a smoked product. There is no smoke ring....but with a little liquid smoke - could you not add the smoke flavor?  What are you guys thoughts on this?
