If you have an older TV without a digital tuner built in, it will go static by Feb 2009. If you go to dtv2009.gov, you can sign up for up to two $40 coupons & use it to buy digital TV converter(s). The converters will cost between $50-70 each.

One more thing: buy the converters as soon as you get the coupon(s). They expires in 90 days.
