The costs of a new kitchen door with new hinges (recommended) is about $50 each, through a local cabinetmaker. A 2400×1200 colourboard from Laminex costs about $150 and the edging costs about $1.50 a metre, hinges around $5 a set. You can normally get 6 doors approx from one sheet of board. So the cabinetmaker is making a tidy profit at $50 a door and your making a tidy profit on revamping your kitchen for under $1000 easy.. 

Also handles are best to buy from the local cabinetmaker too. He can order them for $1 each… Bunnings and the like sell them for a remarkable $10 each…. 

Moral of the story… build relationships with your local trades… they will become vital to your renovations and as long as they are making a bit of money and you are saving its a win/win

Happy 2013 and all the best!
