Hank, have you tried looking for parts or a solution for the Blue Rhino since you liked it? Although I think you will like the lid on the Blackstone also. I am glad I have one on mine.
I have not looked for parts. The problem is that my outdoor kitchen is my primary cooking area. We have taken folks into our house and we share a kitchen with three households.
I simplified things by moving my cooking outdoors. I do most of our cooking on either the griddle or my smoker.
I'll still do smaller cooking jobs, like individual breakfasts in our kitchen.
Also, I have an extended warranty. I would probably pay more for parts than replacing the griddle. It still works. I just have to be careful lighting it so the burners don't shut down.
An example is that I light the first two burners which shut down while trying to light the third burner. This is why I think it is the safety shutdown. The igniters not working correctly is causing safety shutdowns.
When it first occurred, I could not get the griddle to relight and had to move my food to the kitchen.
There is a safety interlock built into the unit.
