Roma are not the “normal” tomatoes sold fresh in American grocery stores.

What are they called, then? Since I took a job overseas over ten years ago, I haven't been in American grocery stores much. What's the "normal" variety called? I distinctly remember Roma being the cheapest, and also worst-tasting, variety, and learned to buy the "on the vine" style instead, but those are the only two that stuck in my memory. What is the one I'm forgetting about?
