Purchased an XPS8390 off of E-Bay, after a few minutes of use, blue screens, worked with Dell to resolve, twice reload of Windows 10 Home failed, blue screens, returned to Dell, repair part unavailable, estimated part availability a week.

Any opinions on if I should request new replacement computer, or wait for repair. 

The 30 day return window from E-Bay will probably be exceeded by the time the repaired computer will be returned to me, and there might be a 15% restocking fee (computer value $1600).

Any advice?
