I have a Panasonic BDT-210 (2010 model) blu-ray player which has built-in WiFi and all the current a/v formats. An excellent player which you could probably get for $100 or less (if you can find them). Last year's model was the 220 and from what I've read is just as solid of a performer as the 210.
Back to Insignia, the only reason I think it is an LG off-brand is way back at the digital conversion when the various STB digital converters were being offered, I picked up a couple of Insignia's with the coupon plan and took one apart cause I was curious
It had identifiable LG components which I was hoping for. The reason being is that I had an LG STB (LST-4200A) for my HDTV-ready Sony CRT which worked exceptionally well for OTA television. That was one of the reasons why I went for an LG LCD when I finally got hip and purchased a flat panel
OTA for us is still dead-on-balls perfect. Anyway, long boring story short, someone said the Insignia's were LG ATSC tuners so that's why I bought a couple for back bedroom/garage analog tv's (and one to "play" with). The haven't disappointed and are still working as well as the full HDTV STB that I had for a few years.
And, to be fair to Vizio, as I have said before, there are lots of folks who have been very satisfied with their Vizio purchases over the years so not everything they make is poor quality all of the time.
