I have not held a BBQ Guru / pit viper fan in my hand. It is rated at 10 cfm and looks like a molded plastic fan / housing inside a sheet metal cover with a sliding damper door on it. Am I close to being right?
Or is it made of metal, with metal fan blades? I was reading about one of the fans (for a Stoker I think) that had a plastic fan blades and a flap door to protect it. The flap door swings open with airflow.
The low end BBQ Guru is just a tad over $200. and probably worth the coin.... just has no "I did it myself" factor like the UDS has!
The PID temperature control / display units can be had for $35.00 plus probes and fan.... and some tinkering. That is what got me started down this road.
