Hast du eine bessere Idee?
Ja, vergiss das Projekt!
Perhaps I was being hasty.
I should have first asked why you want this translation.
Quick, cursory translation - with plenty of awkward phrasing and outright errors - but you at least get the gist of it, cheaply? Then Google Translate is adequate.
So, for what actual reason do you want to be able to read this book?
