I have a five year old Performer Deluxe and I needed to buy another grill.  It was an easy choice because of the versatility and easy lighting.  I got another Performer Deluxe and was delighted to see several refinements.  The shield on the handle keeps it (a little) cooler.  The removable grill piece in the middle is really nice!  I use a round charcoal holder for indirect heat and putting the charcoal in the middle and removing the middle of the grill is perfect.  

The hinged cover over the lighter is aggravating and the timer is useless, at least for me. A probe thermometer would be genuinely useful.

Anyway, Weber - Keep up the good work!  You are absolutely my favorite grill maker.
