While I'm recommending seeds, I'll add Bella Rosa determinant tomato (TGS) to the list... Produced over a long time. For indeterminant, full-sized, the prizes go to Cabernet and Tiffany. Both of these are "hot house" tomatoes... Solid, medium-sized, good disease resistance. You can keep your open-pollinated "heirloom" tomatoes... I'll go with vigor, taste and disease-resistance any day. (OK, if you want an heirloom that does well in FLA, that would be Goose Creek, a southern tomato with good resistance and vigor...)
