Granite vs. Silestone

One of Steve’s contractors is giving us a deal on granite countertops. So last night we went to their web site. And now, we’re wondering: should we do silestone instead?

Here’s the thing: I spill things. Coffee, oil, vinegar, all the stuff that stains. Am I capable of maintaining granite? Steve says, rather insultingly, an emphatic NO. He’s probably right. So has anyone out there actually seen silestone? Used it? Have an opinion?
