Dutch oven and propane gets it done for me. I found a burner at Home Depot a couple of years ago I really like. Low to the ground and wide. Less likely for it to get knocked over. I really don't use the thermometer any more. I started burning the oil trying to maintain 350 degrees. Now, at the start, I watch the oil to see if it is churning. Then I use a couple of "Tasters" to get it right.
When it is just me and the wife, a Fry Daddy is perfect. But, I still cook out on the deck.
