need some recommendations

[gardeninglee]

A gardening friend of mine asked for a recommendation for a tomato that has these characteristics:

1. must be bigger than a cherry and saladette size
2. she has never had much luck with slicers so does not want any big tomatoes
3. must be somewhat sweet and no bland tomatoes
4. productive
5. no late tomatoes

I asked her what tomatoes she gets at the supermarket and she says she likes the camparis.

What would be something good to recommend to her?
