A Hoover 7kg washing machine. Bought it brand new at an auction with a big dint in its side. 19 years later, it's still doing its job, and saved nearly $400 because of that dint. Aussie made and never had a serviceman out to fix it - ever.
One of the best things I have bought is a Sunbeam pressure multi-cooker. It replaces pressure cooker, slow cooker, rice cooker, and can sauté, brown and simmer. The other great gadget is a Breville food processor.
A marriage certificate!
