Buying a new fridge - tips & questions?

Any tips for buying a new fridge? What do you like about yours and what don't you like? Brands good and bad? Shops to buy from good and bad?

Also, when measuring the space you have to put a fridge in how do you know how much room you have to leave at the sides to be able to open the doors?

In my opinion you can't go wrong with Westinghouse - they are made in Australia. We had a 2nd hand Westinghouse for years and only recently replaced it with a new and bigger one to accommodate our growing family. It all depends on how much you want to spend, ours happened to be on sale so was just over $1200 or so and is a side by side fridge/freezer. We don't have an enclosed space so we didn't have to worry about the size.
Check online for deals, Harvey Norman or Good Guys seem to have the most variety. Go and talk to a salesperson and ask about measuring the space.
