I don't think now's the time to be thinking about AR's as a money making investment unless you're really into the buy high - sell low thing.
Not much of an investment if you buy later either. There's no telling when the next "panic" will be and having the money tied up in the back of your safe is silly.
Might be different if you didn't hate the things.
