Bottom line: if you're after an item you've wanted for a long time, pull the trigger while you have no expensive responsibilities like a family, mortgage, medical bills, etc. I'm a recent college grad with a job I love, no debt, and no social/financial fetters, which makes this purchase perfectly reasonable for me. I don't want to inspire anyone to buy something beyond their means - buy what you love with what you have and never spend more than what's reliably in your bank account on frivolities.
