I have finally tired of the poor ATSC tuner in my Vizio LCD TV. The TV is an older 32" model. I have been making do with it, thinking I screwed up the antenna, but I have been noticing some other things that make me thing the Vizio simply has a really bad ATSC tuner.
So, I am taking the plunge and ordered the DTV-5000HD. Given all of the info here and elsewhere, it can only do a better job than the buil-in tuner of the Vizio.
I am not going to steal the Analog converter I use in my kid's room, since I am looking for real HD.
UPDATE: Order place on Sunday. Processed on Monday. Shipped on Tuesday. w00t!
UPDATE: And according to my USPS shipping notice, is now sitting at my front door waiting for me to get home. New toy! New toy!
