Answer: It sounds like your tomato plants suffered some sunburn last spring. This happens to plants that are taken from the protection of an indoors environment and are immediately planted in full sun. It's very important to "harden off" your seedlings. At least 3-4 days before you transplant your seedlings to the garden, put them in a sheltered place outdoors, away from intense sun and wind. Leave them there for a few hours, and bring them indoors. Gradually expose them to a more of the elements each day. After several days, you can leave them out overnight. Then they should be tough enough to withstand full sun.
It may also be that your seedlings were potbound, and when you transplanted them, they suffered rootshock, which further weakened them.
Early Girl is resistant to verticillium and fusarium wilts.
Bush Big Boy is too, and is also resistant to nematodes and tobacco mosaic virus.
Super Tasty is resistant to all of these, plus alternaria stem canker.
Brandywine is not listed as resistant to any of these diseases, but is a hardy heirloom. I'm not sure about Red Satin -- I'll have Burpee contact you directly about that one. Best of luck!
