I purchased one from Radio Shack - 7 inch flat screen with amazing picture - several months ago and am extremely satisified. If you have a lot of wiring where you will use it you will need to buy their antenna as well. Total cost with antenna is around $150.00.
Because I take it to work in case of severe weather I keep it in an old laptop computer case. Perfect fit!
The cost of that Radio Shack tv has come down. Good info. I’ll provide a review of the USB tv tuner when it arrives.
