Well, I feel like a goofball now -- I just found what appears to be the same book available through amazon.com for less $$:

If you're interested, you could snap up that one. Too bad I'm going to end up paying more for the one on ebay, if I even win the auction. Amazon has a few other editions as well that you can find if you search the zshops. There are a few Alpha Phi songbooks and cookbooks as well.
