I got a transplant from a nursery last year. I got two tomatoes out of it, but I think I planted it too late, so this year I started my seeds and will put them in the garden in a couple of weeks. Hubby and I both loved the flavor - deep and slightly smokey. Great on a burger. :-)
The link you sent said they are not real productive, but great flavor. Some of the commenters there said they had good production.
