| The Bottom Line | The Vizio GV42LF HDTV maintains the balance between competitive pricing and good performance. | CNET did not review the Vizio SV420XVT, but we did review a larger model in the series. | The Vizio SV470XVT represents a viable alternative for LCD TV bargain hunters who want 120Hz processing. | Although not quite the best of its breed, the Samsung LN-T4661F delivers very good picture quality with plenty of style and functionality. | |
