Tomatoes with a thick skin - like Roma -are crack-resistant. Most modern production varieties are bred to withstand rough handling which also provides a degree of crack resistance. In our experience, Solar Fire cracks less than any other we have planted - it's also a large slicer and tastes pretty good for a production tomato -- but maybe not good enough for the markets you are targetting.
One way to whip Anthracnose is to green-pick and artificially ripen - but that won't work for you. If you're organic, weekly sprays of Copper Hydroxide (Kocide, Champ Dry Prill etc) will help some. . If you're conventional, use Bravo Weather Stik (chlorothanil) or the real fungis powerhouse, Quadris (too expensive). You can also plant somewhere else - the Anthrac stays in the soil and spreads by rainfall or sprinklers - or anything that brings soil in contact with ripe tomatoes.
Our seed supplier does not list any Anthracnose-resistant variety, but there may be some - unlikely anything but production toms, though.
