Wife and I have had a Yoder YS640 since February 2012 and are very happy with it, no regrets. Often this model is referred to as built like a tank, it is. Made in the USA, 10 gauge steel cook chamber
December 2017 we got a Blaz’n Grid Iron, very impressed with the quality of the build. In comparison to the YS640 it has a larger cook chamber and hopper, center mounted burn pot is easily removable for cleaning and the pro rack system has well over double the square inch grate space. So far very happy with purchase. Made in the USA, 16 gauge steel cook chamber with strategically placed double wall construction.
We purchased the Blaz’n for its ability to cook low ‘n slow 4 grates of ribs for cook offs over the Yoder’s 2 grates. In my opinion the sear kit in the Blaz’n is a disappointment and does not grill or sear with direct heat. We did not purchase it for the feature and will never try it as have plenty of grills for that. Yoder on the other hand has a nice set up, again in my opinion for direct grilling and searing.
Only other experience we have cooking on a pellet grill was doing a few racks of ribs on a
Rec Tec Mini, it performed well for us. Made in China, sheet metal construction.
Have the YS640 and Grid Iron out today smoking meat sticks so got a side by side pic of them.
