Refurbished Or New?

[9mm]

I got a xbox (refurbished) from Electronic Boutique, The salesman which I knew was telling stories says this unit was picked off the line at mircosoft and was tested that is why its refurished. LOL! YEAH right. So I call Xbox and ask for their story. I heard this. Its a new unit inside, the shell is just used. So I ask this isnt a deal where whatever it needed it got and sent back out? My answer was no everything inside is new.
My question is a refurbished just as good as a new one?
I got a 90 day warranty same as new and an option to buy a $15 warranty for 1-2 years.
Would anyone else buy a refurbished one? I have 14 days to take it back.
