Sorry I did not search for this thread before buying mine, but I seem to have picked what most other people recommended. I went for the Bosch EcoLogixx 7 Condenser, which is supposed to be the most energy efficient dryer in the world.
The alternative was the Miele, reason I did not buy was the lower energy rating, cost in and around 1,000 but does last for 20 years. Just in relation to umop3p!sdn's point about being stuck with today's technology for 20 years, it was pointed out to me that software upgrades are available at 40 euro, so technology should not leave you behind.
