It is better to get a good quality appliance which will last longer, than a cheap one which will need replacing within few years.
I've found Hotpoint, Miele and Bosch last longer than brands like Beko and Tricity/Bendix.
For best of both worlds (quality and saving money) try the Comet or Currys auction sites, where you can get new goods at knock down prices albeit with slight dents, etc. Nothing serious and they come with the normal guarantee.
I have dreamed in my life, dreams that have stayed with me ever after, and changed my ideas; they have gone through and through me, like wine through water, and altered the colour of my mind. Emily Bronte
