The Bottom Line The Vizio L42 HDTV leads the affordable big-screen LCD charge while managing to produce a perfectly acceptable picture. The Vizio SV470XVT represents a viable alternative for LCD TV bargain hunters who want 120Hz processing. Panasonic's TH-42PX80U 42-inch plasma sets the picture quality-to-value standard for entry-level plasma TVs. The midlevel Samsung LN46A550 LCD TV strikes an excellent balance between price and performance. The Vizio GV42LF HDTV maintains the balance between competitive pricing and good performance.
