Can someone suggest a similar synth? (or a good alternative)

I’ve recently been getting into music production, especially in Progressive house, and though i’ve got the side chaining, beats and other things down, one problem has been finding a proper synth that sounds anything like I want it too,
I would like one that can make me similar sounds such as in the first few seconds of this: http://www.youtube.com/watch?v=hSbI9O-DY5k
It can range from being very low (like this), to being a bit higher. Also I know it’s a common sound used also by EDX, Adam k, and previously Deadmau5.
so any tips?
PS: I am using logic 9 on mac, and price is a non-issue.
thanks
