This grill setup is great.  I had one of the original Performer grills for over 20 years, and the frame finally rusted and fell apart.  Since Weber no longer had frame replacements for my old one, I purchased  a whole new Performer grill.  Having the disposable propane bottles is more convenient than refilling the small propane tank on the older model.  It took a while for me to get used to the removable center portion of the top grill.  I had been in the habit of removing the top grill to load coals, so when I remove the top grill I have to be careful to handle it such that the removable center portion doesn't fall off and go rolling around on my patio.  I finally realized that I can just remove the center portion of the top grill to load coals, and leave the rest in place.  So, loading and lighting coals is quick and easy, and I can stay with my preference of charcoal over gas without as much prep time getting the coals going.
