My experience has been like all the others who took the trouble to write.  I bought the Baron 590 girl a year ago and the cooking grids rapidly deteriorated and rusted out so that they now have to be replaced.  This in spite of my having exercised care and followed Broil King's recommendations. It's most unfortunate, because, otherwise the grill has been excellent.  It's sad that Broil King would incorporate such an inferior, but critical, part in an otherwise high quality product.
