[MD507]

Which Converter Boxes or Box is the best for the Feb. 2009 Digitial Switch over. I just send out my Coupon Offer, my 2 Coupons should come by Oct. 31. I have 2 Converter Boxs in mind, if they are still availble.
1. RCA DTA800
2. Zenith DTT900

Is one of the those or both Good Converter Boxes?

I have the Zenith DTT900 on the patio TV which I've been using about 6 months. I have it connected to a roof top antenna and it gets a great picture. Very easy to use also.
