The only thing I have is a 'best of' comp which I picked up about a year ago. Joe Walsh was performing live on the Howard Stern show and after they played 'Walk Away', they discussed what a great band the James Gang was and played some other songs. Based on that, I checked out the greatest hits and I thoroughly enjoy it. Don't know if I'd ever get around to picking up any other stuff though.
Love Tesla's cover of 'Walk Away' as well. That too probably prompted me on some level to check them out.
