Not a great deal made in black as yet as it`s a low volume seller . Probably the best out there at the moment which isn`t on you list
is the Bosch KGH34X50 which you can get for about the budget you mention. My next choice from the list would be the Hotpoint.
If you are after a price only transaction then the internet. If on the otherhand you prefer to have the advice and back up prior, during and after the sale then an independant retailer is the better option.
