Check craigslist. I see quite a few used ones on there from time to time that might be half the price.
+2 on this. +2 because I bought both my Webers on craigslist for less than half the cost new and they both were/still are in like new condition. I have one propane Genesis and the other is the Performer propane fired charcoal grill. The guy I bought the performer from was selling it because he said the propane part didnt work anymore. I sanded the spark plug and it worked fine. I love both these grills.
