Best Converter Box?

I have shut off my Directv and looking for a converter box. I have read so many things on many boxes. The info that I have read has not been a real clear comparison between a few boxes. I am in a fringe area and most of my signals are in the 38%-56% with an amplifier. I have a very large antenna and it is at 30ft.

I have on box that is a RCA DTS800. It does better than the first gen digi-tuner in my old tube tv.

I have been looking st several boxes including the Zinwell 970a, zenith/insignia, and the new RCA 800B1.

In real comparison for signal strength is there any difference?
The features of the RCA I like is the unified remote that does the tv and box. The sub channels can be remove from the list, but can be accessed manually entering the channel. Those are great for me. The Ideal box would be a directv menu guide, delete sub channels, and the unified remote. Also, with a good tuner that can get a better signal without breaking up so much.

Does anyone know a box that is under the 100dollar range or maybe just above that that will not a be a junker with a unified remote?

Thanks so much for your replies,

Mike

The roku box is good. I do have one now. The sub channel delete is great, The guide is not a necessity, just what is on would do me fine.

What model is the channel master box? Does the channel master control the tv volume?

Have you compared the channel master to any other box for weak signal stability?

Thanks,

Mike
