We grew Mr Stripey the first year we got here, bought them from a local nursery. They grew into nice plants and the fruit was very tasty. Unfortunately, deer liked them more, and we were pretty much done with them after a month of them bearing.
We tried them again the next year, but we grew them from seed. After planting them in the garden, they grew into monsters, almost 7ft tall. But, lots of rain and poor mulching meant early diseases, and we didn't get a lot of fruit off them, and those weren't that good. We tried them one last time last year, and they disappointed again, so no go for this year.
I've read good and bad reviews of MS, but like folks say in here, it just depends on your location. You could just try a couple plants and find out.
