Well guys, last night I called my Radio Shack in hopes they might have a Zenith stashed somewhere -- you never know -- and the girl who answered said, "Oh yeah, they're all Zeniths. That's all we have."
"Really? They aren't the Digital Stream?"
"Nope, just Zeniths."
I was doubtful, but I ran over there right before they closed.... And of course, they were all Digital Streams.
They did have a tag on the shelf for the Zenith, though, so I guess they carried it not so long ago. The other guy working there told me they had discontinued the Zenith, so that shows what they know.
But I went ahead and bought the DS while I was there. A couple more of our analog stations have gone off the air in just the last couple of weeks, including one that shows our local NBA team, and I didn't want to wait for a Zenith/Insignia. I can't find a Zenith online, and the guy at Best Buy told me yesterday that there are zero Insignias in either the local or the regional warehouse, and he couldn't tell me when they might get more.
I'm actually pretty impressed with the DS box. It gets every channel with no problem -- turns out that the one weak station I was concerned about isn't even a problem at this particular location. I see what Rammitinski is talking about with the resemblance to the old Accurian HDTV box from Radio Shack -- the menus, signal meter, fonts and even the size of the text are all very similar. I never really cared for the appearance of those things on the Accurian, and prefer the look of those items on the Zenith as far as that goes, but that's purely a cosmetic preference. I will say that I think I see a little of the softness the old Accurian had on SD broadcasts, but it's okay for the purpose of viewing SD digital on an old TV. The remote sensor is incredibly sensitive, as someone said -- just point the remote anywhere and the box responds, which is pretty nice and, unfortunately, not the case with the last few pieces of electronics I've bought. The remote controlled the ancient (early 80s?) Sylvania the box is connected to with no problem. I appreciate the analog pass-through on the box because I do have a PBS station and another local station that are still analog, and though it's a little awkward switching back and forth as the box powers down, it's tolerable. Soon I'll replace this TV with one that has composite inputs, so I can just hit the input button on the TV remote and switch it that way. BTW, I've seen the question about why cable is an option in the setup menu on the Digital Stream... Well, mine doesn't have that. They must have removed it somewhere along the line, because I see the space where cable was, but it's now blanked out.
So in summary, I'd still have bought the Zenith if I had a choice, but that's more personal preference for the look of the menus and so forth than anything truly substantial. This box does everything pretty well and the remote is very good. I'm sure it will more than fit the needs of the average American simply looking to pick up these newfangled digital signals.
