Most reliable freestanding freezer

Hi,

I’m looking to purchase a freestanding freezer with a capacity of around 200L. My main criteria is the reliability of the machine, or more accurately, the average annual ownership cost calculated as the (purchase price plus the cost of any repairs) divided by the total number of years I can expect it to last before having to throw it away. I know that there’s no way of knowing how long an appliance will last when buying it, or the potential cost of repairs, I’m just looking for a best guess. On this measure my Miele fridge freezer (MIELE KFN12924SD) is doing extremely well as it cost about £500 in 2010 (it was a graded unit with cosmetic damage) and I haven’t had to have it serviced or repaired once since then, so its cost £45/year.

Which brands would you recommend based on this criteria?

I don’t mind buying a more expensive appliance if it will last longer. My other requirement is only that it is frost-free.

Secondly, are there any retailers you recommend for graded appliances? I previously used Comet Clearance Auctions but they no longer exist.

Many many thanks for your invaluable advice and all the effort put into this wonderful resource.
