Well, there's only the two editions for all four books. The original paperbacks (which definitely cost an arm and a leg. Especially for ones in good condition) and the current hardcovers (which aren't a bad price). There is the new paperback version of OtEotDSoD, but that's the only one with the new covers so far
Only good book series cost arms and legs. I should know. I’ve lost all of them by now.
Hmm...
Well... UH...
At the Christian bookstore around here, you can get the harcover version of the new edition for about 8$.
OH!! OH!!
Try looking on ThriftBooks.com.
They have books for 5$ and under usually! =D
Maybe you could borrow someone else's arm or leg.

I'd say the hardcover versions would be good, but then I'm guessing they are what you mean when you say "cost an arm and a leg"?
