A friend of mine finally got her coupons in the mail, and redeemed one of them for the Magnavox. i asked her to bring it over here yesterday to compare it with the Zenith.
The over look/feel was a bit disappointing, and the signal strength on the weakest channel appeared lower with the Magnavox, but I suppose that could be a difference in the signal strength meters. It still managed to lock onto a viewable signal, regardless--and there were no audible sound issues, unlike the Zenith.
I didn't care much for the overall look and polish of the menu system--the Zenith wins hands-down in this area. However, I love the program guide, which extended several hours into the future, as opposed to now/next with the Zenith.
By far, though, the coolest feature that this box had, that I wish was on the Zenith, was a "still" button, enabling you to freeze the current onscreen image for as long as desired. I know--it's a toy feature, a fun feature--but I still wish that it was on the Zenith.
In spite of the look/feel, which worries me a bit, I wouldn't mind having the Magnavox as a second converter.
