Tomatoes seem to be very variable in our climate
The Boss grew them very hit and miss year on year, one year got an amazing monster crop which got turned into a cupboard of chutney…. followed by a disaster crop the following year
All grown in grobags in the same suntrap spot each year

Tomato yield depends on 'Heat Summation': in order for the fruit to develop and ripen satisfactorily, they need a certain number of hours above a certain temperature (the exact figures depend on the variety). I can't have a greenhouse (shared garden) so my toms (and chillies) are at the mercy of the elements. Last year, after a good start, was terrible in the south east with weeks of cold weather and consequent almost complete failure of the tomato crop, and the ones that did ripen were tasteless. The year before was great, and I was giving the things away.
If you're limited to outdoor growing, I've tried and recommend the first three varieties on this page (unfortunately sold out now):

Being early, you have a better chance of sufficient heat summation, and they seem pretty blight resistant. They also don't require pinching out or anything elaborate in the way of training.
There's no problem saving seed from these, use the method described by Dave Halford above, and save at least two separate batches, just in case.
