I have a Pioneer VSX series (can't recall exact model, 1122 I think) and it has AirPlay built in. I love the feature, although true, no video streaming like you would get w/ an aTV, for wireless tunes, it's great. My model is 1-2 years old and doesn't have built in wifi so I hardwired it w/ Ethernet, which wasn't a problem for me though, YMMV.
Honestly, unless you're a huge audiophile, any mid range (stay away from 100-200) receiver w/ AirPlay will be a good choice. As concrete proof, I bought my parents a mid level Sony receiver for $350 (open box, reg price $399) and it had AirPlay, Bluetooth, & WiFi all built in. For a simple HDMI switch/pass through + wireless tunes, it's been a great purchase. Does it provide the most advanced A/V setup around, no, but it allows me to switch all of their gear through 1 box, provide a wireless streaming set up and does it all without sounding like crap.
