Id check your local electrical stores and pick the salespersons. Read up on reviews on the internet. Consider what exactly you need.
When we bought our appliances, I bought all the same brand (which I would never do again if u want to save money), also bought them all in the same shop for convenience really so only one delivery (again prob wud be cheaper to pick in different stores based on price). We also bought a top of the range stainless steel cooker and to date the oven has only ever been used to store tins as we'v a solid fuel range, we'd have saved a packet by putting a hob only and had an extra press in the kitchen (hindsight is a great thing)....we bought a silver washing machine for the utility (again more money) which has since been replaced by a white one, one ever notices it....as venice said consider the energy usage of the appliance.
