For less than 100 USD ($90 - I just checked) there are several well-reviewed 2230 form factor 1 TB NVME drives on Amazon - specifically, the Corsair MP600 Mini, the Teamgroup MP44S, and the Inland TN446. And though I don’t have one of those drives (I have the 2 TB version of the Sabrent Rocket instead) I speak from experience when I say that the install process is straightforward.
