Hello from a total Roadster newbie (but not roadster newbie) & fundamental questions

[Roadrunner13]

Yes, a lot of people do that and are happy with it. Note, the one you linked is the fixed cord version (40amps) which is only NEMA 14-50. There is a different version with changeable plugs but limited to 32amps.

The old Roadster versions are much more bulky.

The Model S/X are much smaller and convenient but not all revisions work with the roadster.
Older revisions were not all compatible, so whether new or used, just make sure you try to charge your roadster with it and your CAN-SR before putting the money down!
The one with changeable plugs includes 120V so you can leave the yellow cable at home.

Roadrunner13 is right about some of the earlier versions but the most recent revisions are generally reliable with a Roadster. In any case Tesla has been good about replacing it if it doesn't work with your car.
