I just bought a Cajun Injector smoker (Bradley knockoff) for 199. at Wallyworld.  I have used it a few times and it is great.  It has temp control, an internal temp probe, timer and lots of racks like rib, jerky, regular and a water pan.  This thing is solid and well built for a knock off and you can use pellets or chips which are fed through a port on the side.  Alot cheaper to run for sure.
