Hardly anybody has had much good to say about it over at AVS Forum. It's pretty basic and there are several cosmetic variations of it. Also, there's a model that is for using with U.S. Digital's broadcast system that looks the same and sometimes it can get mixed up with the general public model. The one you have to use with U.S. Digital has been a scam on E-bay too. Folks get them cheap for signing up for USD's service and then turn around and auction them off as if it's the general public model. The faceplate has no controls, best not to lose this remote!
I was in Circus City today and they had a $250 OTA reciever that I can picture going on sale for $199 down the road, it was pretty basic but it had bleeding front panel controls! It might have been Motorola...? I'd pick it over WallyWorld's offering even if it cost more, for now. ...or I'd look at the LG models. Best wishes!
Recently I was in the market for an OTA HDTV receiver for my X1, I ended up going with an older model from an established name (Samsung SIR-T151) instead of a newer model from an unknown budget Wal*Mart brand. I did consider it, but only briefly. I have been very happy with the 151 so far.
I personally don't mind refurbished at all, but I found mine NOS for only $10 more than that. The dealer didn't have a good Internet reputation on the ratings web sites but they did fine for me.
NOS = New Old Stock. I got it at Big On Digital. I honesttly can't recomemend them, but they did fair business with me. If you're not happy with the 150 the 151 would probably be an incremental update. Check the new 451.
