You person you!
How VERY TIGHT is TIGHT money wise? Need to give a budget here to work with you. The warranty is absolutely necessary (w/ complete care), think of it as an investment for that big whoops when its about to end.
Maybe you shouldnt be looking at the i9300 if the 40% off right now aint doing miracles for you. Look down at the 6000d and grab all you can.
OR, you could starve it off if its not a school purchase and wait till you can get a good lappy purchase.
