What are the best varieties for market?

Some folks shop the farmers markets for the unusual OP variety. When they buy a tomato, they are actually buying a seed packet which they can plant. The neat thing is they can eat the package the seeds came in and determine if they want to grow the seed in their garden. I know my eye and my interest are always attracted by something different. If it doesn't meet the taste test requirements, I won't grow it. A lady on a different forum reported purchasing a beautiful, large, yellow tomato at a farmers market. Her anticipation built up all day. When she got home, the first thing she did was slice the yellow tomato and was very disappointed to find it tasted like low quality cardboard. The tomato seller made some money on the one tomato, but he lost a customer. She felt the grower had cheated her by selling her a pretty, but inferior quality product and she will not return to his booth.
