The lesson I learnt with kitchen appliances, don't go for the expensive models on the hope they'll last longer/be more repairable.
We bought a fairly expensive oven, which broke 3 years down the line. We couldn't get a replacement part for it, so had to effectively scrap an £800 oven after 3 years. The manufacturer offered us a half-price replacement, which lasted 2 before it gave up the ghost - we didn't even bother repairing it and sold it for spares.
These days, I buy cheap. I swapped my £800 oven for a £200 one. It does exactly the same job. Yes, the door isn't as smooth, and the shelves are a bit flimsy, but I'm not going to care when it breaks in a couple of years. The best part - when cleaning it, I noticed a tiny label which had a well known brand on it. Barring a slightly different front panel, we found out it's actually a "rebranded" oven from a big manufacturer, just without the profit margin I guess.
