There are plenty of converter boxes, the problem is they ran out of funding on the coupon program.
Really, if you were warned for well over a year (this was already extended once and has been in the works for over 6 years now) and you never got around to requesting a coupon until one month before the drop dead date I'd say you're tough out of luck.
Even funnier, they extended the deadline but didn't give any more money to the coupon program, so, what exactly changed? In addition, the stations can still choose to shut off analog on the original date, many of which will because it's expensive to power both signals.
All in all, it's a stupid waste of time and I suspect they have MUCH better things they can be doing like figuring out how to spend a couple more trillion dollars we don't have...
