Hard to find an 8" Dobsonian?

The only one I can seem to find that's in stock anywhere is a Celestron Starsense Explorer 8, but that comes a whole smartphone integration system that, though may be convenient, I'm not really interested in. I'm just looking for the most basic 8" dobsonian scope. Any idea why the 8" in particular seems to be out of stock everywhere? Post-holiday season maybe?

Models I'm looking at specifically are the Apertura AD8 or the Sky-Watcher 200P. I was very disappointed to learn that Orion went out of business as the XT8 would also be exactly what I'm looking for.

Any suggested alternatives to these?

EDIT: I'm in the US
