Check some of the thrift stores, goodwill, and even flea markets. that's where i spotted my Samsung SIR-T451
HDTV Tuner which does
OTA and QAM as well, and i got it for the beautiful price of $5. they thought it was an old cable box lol!
The SIR-T451 (also check ebay), has many different outputs, one of which is your average component video out, and it also has
RGB VGA-out for a computer monitor, or even a
DVI output. sadly since it's
HD it's kinda sad that there's no
HDMI out at all. and the switch which changes output from 480i to 1080p is not remote-control capable, instead it's just a switch in the rear of the box next to the Channel 3/4 switch.
