The only 'good' RCA-anything i got which still works is the 13" Color XL-100 TV in the bedroom. granted it was made in USA then and it's manufacture date is 1979.
I don't have experience with Venturer and i'm sold on Magnavox since they appear to work great and i don't like buying a box i may or may not like and then end up trashing it. i hate throwing things out into the garbage.
The only other box i got that works excellent is the Samsung
HD Tuner. but those are expensive new and i was lucky to find one in a flea market for $5. they didn't know what it was lol.
it all depends on how far away you are from the towers too. some boxes are fine if you live within ~20 miles of them (such as the Zenith or DTVPal) but some people live more than 30 miles away and are are on areas with hills or trees or buildings. those will cause all sorts of problems with boxes which are not tolerant of signal fluctuations within a certain range. also i do NOT recommend using the cables packaged with the boxes. they're inferior and will cause more problems than the antenna or box could ever do. a lot of times replacing the cheesy quick-connect RG-5 in favor of high-quality RG-6 Satellite-grade cable works wonders.
