Gorenje produce a good range of refrigeration without spending an arm and a leg. They will come with a full five year warranty as well, you can see the range here
available from independant retailers. The models to look at end in DE.
Next up would be Bosch and Siemens (same stable) good quality products German design and led with a two year warranty.
Then at the top would be Miele and Liebherr. Miele are very good appliances however due to the high price of spares and gaining tech info is very slim unless you are a Miele service agent.

Liebherr specialise in refrigeration so be prepared for a higher price per unit.
