Cheap BBQ grills can be a good investment for infrequent cooking. The most important thing to look for is a stable grill that will not tip over while it is being used. Grills with folding legs are generally not very stable. If the grill uses gas then it is important to check the nozzles to make sure gas does not leak out while the grill is in use. Many cheap charcoal BBQ grills can last for a few seasons and then be replaced at very little cost.
