Bummer.

I called up a bunch of the local San Jose California Costco locations where
these are the only two "modems" they sell nowadays at any Costco.

Almost no Costco has the $180 unit in stock anywhere locally (where they
have units of 1, but that means it's not really there), where it's also
sketchy even for the $150 unit, so I have to look elsewhere I think.

Any recommendations on a brand/model of modem for Comcast basic 50Mbps (or
thereabouts) Internet-only service?
