Just ordered a CrayCort CI grate (http://www.cast-iron-grate.com/) for the trusty Weber kettle (mans most perfect 20th century invention aside from the ziploc bag). Fits perfectly. Got a few accessories - The grill pieces pop out and one can be replaced with a flat griddle. I also ordered a handle to remove the grates - see below.

The "handles". I ordered 1. They sent me a box of 16. What to do with these? I could send them back, but they are heavy and shipping costs wouldn't be worth it. I could sell them on eBay for 5 bucks a piece - they cost 10. 15 of them would be 75 bucks. Almost pays for the grate.
Well, either way I'm very happy with the quality and the speed at which it was shipped. I see some nice thick steaks in my future!
