I have two eggs. With almost 12 years of use.. I use to sear mostly..Best baked potatoes. It doesn't take me long to light an egg and get it up to temp...No concerns re:electrical, as you know..The egg does take getting used to. Once mastered, it's a no brainer, for most of us.
My first pellet grill (actually a smoker) was a Traeger,Lil Tex. I found it did well in warm weather cooking below 350º. Given time with not too cold weather and no or low wind, 400º could be achieved..Most all my cooking was done @ 325º or/and in the smoke mode. I felt it was being stressed cooking @ high temperatures...I put up in November and back to work, April due to the cold..The eggs kept on working. Had the Traeg' for 5 years..There were a few problems; PM me if you are interested in them.
Last June, I got a Memphis Pro - well, no where anything like the Lil Tex..Gets HOT fast, hot, cold, rain or windy. It is so easy to maintain, almost too easy. There is a direct flame insert (small in size),to boot..Pellet consumption is low. Overly designed and well built. All stainless so there rust isn't a concern...It was a hard decision to make (the purchase)..It comes back to your statement about cheap pits. They cost more.
Taste wise;I don't like the taste of broccoli cooked over charcoal. It's good in a pellet pit..
Maintenance is required on any pellet pit with some being easier to service, such as regular burn pot cleaning, keeping the drip tray clean and scraping out the grease trough and bucket(not a problem on the Pro).. Pellets, fins could be a problem if not controlled and they must be kept dry.
If there way to see the pit(s) you are interested in, in action would answer a lot of questions I an sure..That is; start-up ,cook and clean. Have a good look and ask questions..
