I have had excellent performance from the Samsung SIR-T451. While the earlier models had reliability issues, this one has been flawless for over a year. It also works with standard rabbit ears as far as 25 miles - have not tried at further distances. The only issue I have noted is that the video output is really for a 16:9 screen. If your Sony is a 4:3, it displays gray bars top and bottom, which can be annoying.
