I'd just browse reputable online resellers like Adorama. Sweetwater, B&H, and even Guitar Center also have sections for used equipment. They are reputable and usually have free shipping if you decide to go that route, which will be important for a chunky boy like a receiver. Although that one I linked seems to have sold in the last day, so inventory will fluctuate a bit.
But for your needs, I think you'll be happy with most name brand products. Plug it in and enjoy! You can go down the audio rabbit hole like I'm sure
@Electric Eric and I have done many times, but ultimately what makes a good product is if it suits your needs and is easy to use. Having the fanciest receiver that your wife and kids hate isn't going to help anyone, so I always steer people into the path of least resistance.
So now that we've had this insane talk, just buy that one from Best Buy and have a happy life.
