You're all missing a very important point: If you can't figure out a way to scrounge up $300 for a toy, your credit is probably so horrible that anyone who would loan money to you at below 20% interest is a complete idiot.

You've missed the whole Credit Crunch because 'complete idiots' lent money to people who couldn't pay it back, right?
If by complete idiots = US government then your pretty much correct.
