I am sold on indeterminate tomatoes; it's all I ever plant anymore. The abundant, continuous harvest is well worth the trouble of providing support (a cattle panel arch works perfect for me). It is hard to find indeterminate sauce tomatoes, but my reliable favorite is called "Gladiator Hybrid" from Burpee. Almost identical to Roma, they are large and flavorful fruits. The only drawback is that as a hybrid, you can't save the seeds. If you try, the resulting plants produce very small fruits. Tip to take advantage of the continuous production: after you start picking, keep them in the refrigerator to slow further ripening (or even freeze them) until you have enough for your desired batch size for canning. A side benefit of freezing is that is makes peeling a snap - the peels will slide off easily as the outside first begins to thaw.
