Buy the Weber, and 10 years from now, it will still be performing like new. If any parts wear out, just call Weber. If they're still under warranty (super long), they'll send a replacement right away, no hassle. They probably won't even want the old part back. If it's out of warranty, you can get replacement parts anywhere. Remember that all that fancy exterior SS doesn't do a thing for the grill's cooking ability. You need even heat across the grill surface, the ability to get hot enough to sear, and a good solid design. Weber has all these.
Buy something else, who knows how long it will last, and good luck on replacement parts
IThe burners are cast iron not some thin pipe like the Jenn Air for the same price.
Cajumcook, aren't you concerned that your cast iron burners will quickly rust? Between humidity and the frequently acidic juices from meat, it seems to me that they will be rusted in a few years. I understand the reason for cast iron grates, but it seems to me that burners should be brass or SS to avoid rust.
