It'll come, don't worry. :) But Gabbo is right - avoid credit cards or loans... they're bad. Unless of course you've got the money to pay the bill off when it comes. Interest payments are painful.
Lol...I always used to tell myself I'd never use a credit card for anything unless I'd have the money very soon after...I have a lot of friends who maxed a few cards by the time they were in their mid twenties and it really sucked.
I even had a friend who bought a video camera, paid the minimum for at least 4 years, then when he was a bit older he went to pay off the rest and realized he hadn't even made a dent in the principle! haha. By then the camera was so old it wasn't even worth owning.
Oh well, I'm a Commerce & Admin student so I've learned lots about interest and how it can screw you around ;)
I think I'd still buy it on credit though seeing how I can make up at least half of the cost selling my current monitor and a few other things, and then during the summer I'll be making like 15 bucks an hour.
