I have a PG500 made by Cookshack in good old Ponca City, OK. It uses older tech temperature control, which isn't as precise as the more electronically complex units have, (less bells and whistles) but it does a solid job of it, once you get a handle on the settings needed for your cooks. Had it for 5 years now, and it has been bulletproof.
Not cheap, but made by Okies, and when you call support, the person on the other end says "howdy". Totally happy with it. The Yoder as discussed by
@Coolfogg is a fine cooker as well, and made in Kansas (if memory serves). Almost pulled the trigger on that one.
I view with much skeptisism any manufacturer claims of a pellet grill doing a good job of searing. Like
@Coolfogg , I sear in cast iron when needed. One thing that is unique to the Cookshack are the multiple cooking zones, which I use for sides (e.g. baking potatoes on the high shelf while smoking steaks low). And since it is built like a tank totally of SS, I have zero rust - and I live on salt water.
