Where to buy a burner for a gas barbecue grill?

The burner on my gas grill is completely rusted through. Kinda useless like this. Somebody suggested I try Home Depot in Guad... but they didn't have replacement parts.

Anybody have any ideas?

Berto, I had this same problem. I found that most of the local hardware stores carry burners but none of them fit my grill. So I had a iron worker make some from scratch, they are still working just fine...

Saw a store today in Guadalajara on Pedro Buzeta near cross street Cairo (just north of Plaza Mexico) that has a wide selection of burners for sale. Sorry, don't know the name of it but it is on the west side of the street.
