DIY. Find a big 1/2 barrel (50L) beer keg. Used one. I think it will be less than $100 or even free. That kegs made from good thick austenite food grade stainless steel. Cut it as you need, add a legs and you will have eternal BBQ.

Also, you could use a drum from washing machine, but they made from thinner stainless steel.

Stainless steel looks like some banned material for making goods (especially cars, but it is separate story). Yes, it is more expensive, but it is not a problem if you want a really reliable outdoor thing.
