Nao - we're in the market. Which model works well for you? Is it quiet?
Bosch appliances come in two lines -- Evolution and Integra. Evolution is their freestanding model and Integra derives its name from integration with cabinetry. Integra line can accept custom panels to seamlessly match with the cabinet doors, and to that end, the controls are usually hidden from the view.
Performancewise, there is no significant difference between comparable Integra and Evolution models, but Integra comes with a higher price tag (the difference is most significant in their refrigerators).
I'd go with their mid-line models, the 500 series. You pay the premium for getting their top-of-the-line 800 series without significant performance gain. If it strokes your ego and self-satisfaction, then by all means go for their top models, but Bosch appliances have quality to begin with that even their entry model guarantees performance.
Between Integra and Evolution models, it is a matter of your taste; how you want the dishwasher to fit into the kitchen. Evolution models will let you monitor the progress while Integra with integrated display will remain discreet. In fact, Bosch dishwashers run so quiet that for their Integra models, indicator lamp was added to illuminate the floor at bottom right corner of the dishwasher during operation to prevent people opening the door while it is running.
In the house we sold, we installed Evolution SHE58 (800 series entry model) and was quite happy with it, but in the new kithen, I'm planning to go with the Integra line because the door handle will function as kitchen towel holder.
Also worth a look: LG (sleek and very high performing, but the guage and finish of sst panel seem less refined than Bosh). Whatever the case, don't go for the drawer models (Fisher Paykel - the Range Rover of appliances).
