Carolyn, there is no need for you to buy tomato plants. You happen to be a global moderator at a place called "Tomatoville". There is no way that the citizens here would allow you to go a season without some heirloom tomato plants.
Just post in the 'Wanted' section your above story and many of us will be more than happy to send some plants your way. I bet that you get so many offers that you could pick and choose your varieties to grow.
