As an alternative to cobblelock, with far less maintenance and a cheaper install cost, i'd recommend pattern imprinted concrete.
We just had my mother-in-law's driveway done and the result is fantastic. After much deliberation and fact-finding we went with a company called Procrete (northside based). Their price was good, not the cheapest, but far from the most expensive. We checked references as well, which was the deciding factor in the end. They were booked up 3-month's in advance, which I guess is also a good sign.
