Since posting this question, I've come across the Scanpan double-burner grill pan. It's part of their newer nonstick line and can be used with metal utensils. Amazon has it for $119.99, free shipping. But I can't find a single review of the pan, and it is a little bit smaller than the two I was considering.

If anyone is familiar with it, I'd love to know what you think.

The Wisconsin Aluminum reversible nonstick grill-griddle is great and costs about $50. I got one for a friend for Christmas and she loves it.

Thanks, brooksiefan. I have seen that pan. But a couple reviewers on Amazon mentioned that its nonstick was a bit weak. One said that when he/she cooked a steak on the grill side, with the required fairly high heat, the coating on the griddle side underneath burned off. Granted, the person may be a lousy cook, but it left a doubt in my mind.

This follow-up is a bit late, but I have the All-Clad LTD version and it produces very tasty (and visibly grilled) results. I've used it for meats and vegetables and have been very pleased with it.

The only problem is splattering, which would probably be a problem with any grill pan. For certain foods, I line the stovetop with foil beforehand to catch it all.
