For $1K budget, I would get the $1,500 Denon X4300 on sale brand new for $800 on Amazon.
If you desire external amps, with the remaining $200, I would get the Crown XLi800 200W-8ohm/300W-4ohm stereo amp for about $200.
If you desire more channels of external amps, get the Denon X3300 brand new for $600 and get two of the Crown XLi800 amps for 4 Ch of amps for your front 3 speakers.
Best Buy will price match Amazon if you want to buy locally. If anything goes wrong in the next 3 YR, you just have to bring it back to Best Buy and they will take care of the warranty repair.
I don't have zero luck with refurbished Denon, but none of my new or "like-new" Denon I bought from Amazon have ever malfunctioned. But buying it locally at Best Buy may give you a better peace of mind.
