sorry Dyson 2 drums - I miss-read your comments.
I know what you mean now, one thing I regularly noticed is the old Hotpoint sensors were all over the place, my VTD20 would regularly over dry, and regularly under dry. However what I was saying was, the new dryers with the electronics such as the TVF770, and I presume TVAL, TVPF ranges all dry to perfection with the improved sensors which actually work. I know that the sensors will wear out with age, they all do, even Miele's, so can't really fault it on just that!
The Zanussi in Aquacycle's link looks OK, and has flexibility with the venting, and it has some drying programmes, but on experience with Zanussi, Cupboard dry leaves items wet, not fully dry like the Hotpoint, Plus it isn't available in Black/Silver.
