I'm growing Buckbee's New 50-day tomato, this year (2019). It has decent-sized fruits with thick walls and mild, but good, flavor. The plant is small and has an open habit (so you can see the fruit without moving leaves or branches). The plant was shaded by other plants; so there was little risk of sunscald.
The first fruit was ripe on 26 July. Here are some pictures of it.
