Don't forget to check out Blazin Grills
I have a Grid Iron, my buddy has a Grid Iron, inlaws have a Grand Slam, and another friend has a Grand Slam. I've cooked on them all.
Very well built units, heavy duty and American made.
It used an Ortech controller that is different than the Treager (much better) but if a person wanted to, it could easily be replaced w/ a PID or SSII for more control, but after learning my pit, I just play w/ the P settings and have not had any trouble since learning it.
Probably the best feature is the pull out fire plot for easy cleaning and easy re-ignition if you were to ever experience a flame out.
Lot's of features and also lot's of options, especially powder coat colors, to truly make a custom grill.
I plan on ordering the roller grates, sear option, and hood insulation kit for mine.
I got black, but I'm thinking of taking the lid and stack off and having them chromed!
I've put mine to the test many of times in the last 6mos w/ running 4-500lbs of pellets through it.
My largest cook on the Grid Iron was 9 bone in pork butts totaling 88lbs.
Good luck on the hunt for your pellet grill!
