I grew Stupice (spellcheck insists this is Stupid) several years ago. It was ok. I got better results last year from Matina and Moravsky Div, both of which didn't do as well in a new location this year. Bush early girl was a bust. Next year I'm going to try Kimberly (or Kimberley?) which one commenter says is better than Stupice. All have medium or small fruit, so if you are just looking for similar results, there are many cherry tomatoes with 60+ day maturities.
