I almost forgot about this thread!
Here's a little up-to-date info about what's going on with my tomato plants...
Well, I planted more seeds for this year's garden. I didn't get the Marizol Gold or Maylor Roth's Orange Brandywine varieties I mentioned above (maybe next year), but I planted five varieties: Ashleigh, Aunt Ruby's German Green, Carbon, Crnkovic Yugoslavian, and Estler's Mortgage Lifter. All but the Carbon variety grows in the 1-3 pound range, and are all supposed to be very tasty tomatoes. Particularly the carbon which is a brownish color and is supposed to be one of the best-tasting tomatoes you can grow. I am also looking forward to the Aunt Ruby's German Green because it's said to have a sweet, tangy, and spicy flavor!
Anyway, I started my seeds on the 22th of March and they broke out of the soil on the 26th - 3 1/2 days later! They've been growing quickly ever since, and just this past Thursday I repotted them into larger containers once their "true leaves" started to form. Here's some pics:
