the grill as shown in the photo is built of very light gauge stainless steel.... the lid is kinda flimsy and flexible as it does not have the extra heat shield/lid liner built into it...
another thing about the magma grills is, they are tested and designed to stay lit in the wind... regular outdoor grills are not, and usually will blow out in a bit of a shifty breeze.
I am assuming the one in question has no wind baffle to protect the flame.... but thats not to say it wont work or something couldnt be added.
harbor freight use to have one like this or almost identical to it, on their website...
one caution in buying an off brand stainless grill, the magma brand has a stainless burner... this is the only brand I know of that will stand up to the marine enviroment for any length of time... especially when grilling oysters in the shell. the salt will ruin a regular steel grill in a season of good use...
