Unlike ProStar, I LOVE refurbs. It means it was checked, sent out to consumer, something went wrong, so they fixed it and RE checked it. I've had 3:1 more problems with "new" gear than refurbs, to the point I intentionally look for refurbs when buying electronics.
The only down side is the warranty is usually CRAP for refurbs (you'll get 90 days instead of a year or something!!)
As for Samsung, my next laptop will be one. My son has a Series 9 and it is solid and aesthetically gorgeous. A lot of laptop purchase other than specs is appeal, since unlike a desktop that gets shoved under a desk, you'll actually SEE your laptop on a daily basis.
