I searched till I found the best price (once I worked out that it's well worth comparing prices which include delivery), and AO came out best.
I ordered (separately) a Miele integrated Oven and a Miele integrated microwave.
Both deliveries arrived on time as promised, and the guys who delivered were friendly and helpful.
The Miele equipment is expensive, but I like its understated quality, and it's built to last.
Good stuff!
