I bought my TSR-7810 from Costco a few years ago, and it's been great. Though it seems like Costco is no longer stocking Yamaha AV receivers (or any AV receivers for that matter). At least, none are listed on their site currently.
If Yamaha updates their receivers for AirPlay 2, I'll probably buy another one for my living room (current one is the basement). If not, I'll likely look to a Denon.
