I agree with @riceke. I have grown Big Beef for a number of years (around ten?) and only once was I disappointed with how it grew. The first few large fruits are as pretty as a tomato gets and the flavor has never disappointed me. I always try to grow a few new tomatoes every year and if the new ones are better I keep growing them and get rid of an older one. That's why it's amazing that I have grown Big Beef for as many years as I have.

I prefer a determinate slicing tomato. Last year I grew Starfire, which is determinate and larger fruit than Celebrity. Great tasting as well. I ordered the Starfire seeds again and plan to have few of this variety this year. Ordered them from Victory Seeds. Funny thing, Starfire was developed in Canada in the 60's, for prairie conditions, and the only place I found that sold the seeds was in Oregon
