I picked up a Pro 22 ( my third, don’t ask) . I’ve had nothing but problems with the temp control.  Traegers replaced the temp probe, controller, and then send a whole new fire  box which is essentially the whole grilling part.  It still swings to 455 when set at 350, I don’t trust it to leave it alone to cook which  is one of the big attractions of pellet grills for me. I think that their Chinese factories quality control went down hill. The other two I’ve had worked spot on, I still have one of them and never get more than a 15 degree swing up or down from set temp.
 
	I  have not used a Pitboss, but they are a lot of grill for the money.  I’m wishing now I had gone with one.
