I'd put in a bit extra for a Bosch washing machine. As for a microwave it depends on how big you want it and what you want it to do. They can last 2 years or 20 years so I'd go with one that fits in the space.
I spent like $30 or $40 on a second hand Samsung microwave oven 3.5 years ago and I've been very happy with it, not entirely sure the pricier ones make much of a difference. Washing machines on the other hand, definitely go for quality. I was cheap and got a Beko one that's okay but it does sometimes unstick itself from the floor and get rather violent even when I haven't overloaded the thing.
Thanks Just_kitten, will check out cheap options for microwaves. For washing machines, Bosch seems popular here so I'll go with that, and avoid Beko π
Love my Fisher and Paykel front loader. It's my first front loader and I'm really happy with the job it does.
For a microwave, don't get sold on all the extra stuff if you're not going to use it. I use ours to defrost stuff, reheat meals and melt cheese so I got a basic Samsung. Go for decent wattage though.
Happy with mine too. I would argue the premium models (with lots of cycles and buttons) aren't a necessary investment. No matter the brand I think spin cycle speed is important for efficient drying, mine goes up to 1400 which is a great start for dryer or hang drying.
