Christian, quality block paving is the way to go. nicer all round and looks the best imo.

Babscossie, Sounds about right, also watch out for some stupid guideline with regards to the open entrance to your driveway once you have a drop curb or have lengthened your current drop curb.
At my house its a open driveway right across the width of the house with a single size drop curb on the right hand side. When we applied to widen the drop curb not only did they want just over a grand for the job, but they also stated that we would have to build a certain length wall.
