I went to Record Room a few times during work-related trips to Scottsdale, and it's definitely one of the things I like most in the area. Their selection isn't enormous since it's not a very big place, but what they do have is in amazingly good condition and affordably priced. I got a lot of great records here, and they'll conveniently ship them for you very cheaply, so I didn't have to worry about taking them on the plane. The staff are low-key but friendly, and generally allow you to browse at your leisure without stalking you or constantly asking if you need help finding anything. If you're visiting the Scottsdale area, be sure to check it out!
