inasinman,
do yourself a favour and start pumping money into investments first. when your after tax investment cashflow is equal to or greater than the cost of owning your toy(including ongoings) then, and only then should you consider buying your toy. dont get frustrated because you cant have the "toy" you want today. if you invest wisely and maintain discipline, there will come a time when you can have any toy you want.
btw- this also means that you do not need to buy an x-box, PS2 or the like
