My suggestion is get the Latest 65nm chipset XBOX 360,
this is because the new one is very stable to hardware failure already,
I agreed that the Old model Xbox 360 quality is really terrible.
But,if you have a Newest (Falcon) xbox 360,you can notice the difference,
after 4 hours of straight playing,your console just warm a liitle bit (not even warm)and not like before
play only 1 hour and the back is hot like pan,your mum can even fry egg on that.Haha!!
However,it is a fact that the newest model 360 is definately far more relieable than the old ones.
But one of weakness is 360 the sound is very louder compare to PS3.
Anyone agree with my point of view?
Thanks for your reply!!!!!!

why take the risk? thats like saying I should buy a car which is on its last straws (it has engine problems), no doubt it will break down, but it still works now, so you  should forget about all the problems in the future.

When I buy stuff I want it to work; I would never invest on something that you know breaks easily, that is just crazy.
