That monitor does double duty as a PC monitor and a TV monitor. It has standard TV inputs. If you don't have a TV, you should get that.
But you can get a monitor that's just a standard PC monitor for a lot cheaper. In fact, for about the same price you can get a 20" widescreen LCD. A 20" screen will be much bigger than a 17".

There's one of the more popular ones, a Dell 2001FPW.
I apologize if any part of this post did not make sense. I have been awake for 30+ hours (Working on a video, no less ). Ah, the wonders of caffeine. Mmm, coffee...
Edit: That URL a few lines up in my post was pretty long; it was stretching out the forum tables which is a big no-no. I changed it to a link for ya.
Edit again: I didn't realize that price for the 17" LCD is not in US dollars. I don't know how USD compares to AUD, so I actually don't know how expensive it is compared to the one I showed you. I am tired.
