Thanks everyone for responding so quickly. Reading the responses, reviewing this site more carefully, and doing a bit more of my own research made me very glad that I hesitated before ordering another K. Although I thought I did not have a real problem with my K, (like tiles falling off or serious cracks) I guess the warped main grill, the lump saver that fell apart, the inability to get my stainless steel parts back to shiny, and the frequent need for band adjustments are problems that may be avoided with a KK. The bright side of this for me is that my K still looks very nice, so I should be able to sell it fairly easily after I replace the warped and broken parts which I have already ordered. I hope to be cooking with a KK within a few months.
