I went on a shopping spree this week looking for an outdoor grille, one similar to the bottom of a turkey fryer. Walmart did have a couple of fish cookers but the one I looked at seemed a bit to light weight and it was also top heavy. And, no where on the box nor in the instructions did it say how many BTU the unit was.
I found a few on line that look like they would be great. They were advertised as 18, 500 BTU, some had jet burners and some had regular burners.
