Amazon lists used copies of the current edition from $36.92 used, up to $42.89 new. That'll break the bank! Now all Rhino has to do is get together with three-Java programming friends and share the cost. At under $13.25 each I feel quite sure Rhino can afford to read the book, right, Rhino? Hm? Or he could go to one of those bookstores with a coffee shop and read it in the store for free. The excuse "I can't afford it" is quite weak. Come on, Rhino. If you're serious about Java programming you'll find a way to read this book, if no other on the topic, and right soon. Otherwise it's back to, "Would you like fries with that?" -- Lew

And that's no joke. I am indeed serious about Java but I have to eat and pay rent before I can indulge the luxury of buying a book that I don't absolutely need right now.... Once I'm gainfully employed again, things will look a lot different. -- Rhino
