| The Bottom Line | Despite our usual picture quality quibbles, the well-equipped Vizio VO47LF 47-inch flat-panel LCD stays true to the company's good-value reputation. | The Vizio SV470XVT represents a viable alternative for LCD TV bargain hunters who want 120Hz processing. | The commendable picture quality of Sony's entry-level 120Hz-equipped LCD makes it a very good value. | Sure, it has a few flaws, but nothing fatal prevents the local dimming, LED-backlit Vizio VF551XVT from exhibiting excellent LCD picture quality for the buck. | While not up to the picture quality of Samsung's topflight models, the feature-rich, uniquely styled LNB650 series still outperforms most LCDs on the market. |
