Guys there's NOTHING wrong with responsible credit.....and even carrying balances. Heck we financed our last vehicle purchase.....even though we didn't have to. My ($_____) works for me in better ways (in other places)than the interest rate we received on the vehicle.
It's also imperative that a credit history be built for you when there comes a time when you NEED to use it (say...for that home purchse...... or for things like boats, automobiles, investment properties, etc...). Cash is not ALWAYS the best payment method.
We have to get out of the mindset that credit is a dirty word. It's a valuable toolfor a fiscally responsible person.
When someone's offering you credit at a rate of 5%-8%.....they're doing you a favor in most instances. How much can you expect to receive (on return) for that money if you have it working for you somewhere else?

Sometimes it's not even a fine line.
I will say that it's admirable that we have so many that think about this, though. Very admirable.
