I would suggest purchasing a Silver B that has the PCI(Porcelain Cast Iron) grates. Home Depot sells them exclusively with them included. I purchased my Silver B a while back and when my standard grates started to show wear, I upgraded to the PCIs for about $60, Home Depot stocks them. My flavorizer bars were very rusty so I got the stainless steel flavorizer bars as well. Something to think about in a few years when you've got your use out of the standard flavorizer bars. As far as upkeep, there isn't much to worry about. I do a burnoff immediately after grilling and shut off the grill. When I use the grill on the next cook, I take a brass brush to the grates and everything comes off with ease. You'll love the PCIs, they sear very well!
