I'm in the no-Runners'camp too.
Have grown a few this year, but the kitchen and dinners aren't interested, so will drop from the seed list next year.
We grow some conventional "cylindrical" French beans, but also Suttons Limka - a climbing French bean with flat pods and definitely no string!
(I don't think the taste is the same as a Runner, but I have only one vote!)
There is a similar flat-podded Dwarft French bean called Masterpiece. Going to try some of them in the greenhouse for a late Autumn crop.
