If you're really in love with that particular variety, it is possible to turn it from a hybrid into an open-pollinated variety within a few years, 3-4 I think. Save the seeds, grow them out next year, select the plant that is what you want and save seeds from that plant. Once you get to about the 4th year or so, your saved seed should all be true.
I'm trying Mountain Princess this year in my high tunnel as an early tomato:

I'm also trying Ballada:

Both of them are short-season determinate reds, similar to Applause
