Alternative or reprint of Carter's "Finite Groups of Lie Type: Conjugacy Classes and Complex Characters" I would like to learn about character theory of finite groups of Lie type and some Deligne-Lusztig theory.  The classic textbook on the subject seems to be Roger W. Carter's Finite Groups of Lie Type: Conjugacy Classes and Complex Characters (Wiley 1985, reprinted in 1993 in Wiley Classics).  Sadly, this book is out of print, and while second-hand copies can be found, they sell at a ridiculously high price (e.g., this site has one for over 1200€).  To make things more problematic, the same author wrote another (earlier) book with a confusingly similar title, Simple Groups of Lie Type (which I have), and which tends to come up whenever one searches for the Finite Groups book.
So, two questions:


*

*Is there a (finite!) set of textbooks and/or introductory articles whose union covers the same material as Carter's Finite Groups of Lie Type?  I have a copy of Digne & Michel's Representations of Finite Groups of Lie Type, but it seems (a) much harder to read, and (b) less complete (which makes sense as it is over three times shorter); are there other texts which might fill the gaps?

*(This is not a mathematical question, but I hope it is nevertheless allowed here:) Is there any hope of persuading someone (whether the publisher or author, whoever holds the rights) to republish this book?  The fact that it is still considered a standard reference, especially if question (1) does not have an answer, and the fact that used copies are so expensive, suggests that there is some demand.  But I don't know if the author is still mathematically active, or if Wiley still has the rights.
 A: Concerning the books by Carter, both have since been reprinted by Wiley in their "classics" series, though availability and cost right now is a serious question mark.   The 1972 book is limited in scope, emphasizing Chevalley's 1955 approach to constructing simple groups (but over arbitrary fields).    The 1985 book is considerably more expansive, emphasizing the Deligne-Lusztig characters and related matters about algebraic groups such as conjugacy classes.   Two drawbacks: there are some mistakes (still uncorrected) and there is no treatment of the many further refinements by Lusztig and others.     As Nick points out, Cedric Bonnafe's more recent Springer book on $SL_2$ over finite fields is well worth seeking out, in spite of its limited scope.
Anyway, the most recent MathSciNet reference for the 1985 book is here.   Part of the problem with Carter's 1985 book is that he himself left mathematics some years ago and is now quite elderly.    But the book does have a lot of detailed information which is not readily found elsewhere.   It's a subject which deserves a fresh textbook treatment.    Good luck.
ADDED: Maybe it's worthwhile to point out that Geck and Malle are in the process of writing a book of their own about the characters of the finite groups of Lie type: see their preprint of Chapter 1.
A: Malle, Gunter; Testerman, Donna. Linear algebraic groups and finite groups of Lie type. Cambridge Studies in Advanced Mathematics, 133. Cambridge University Press, Cambridge, 2011. xiv+309 pp.
"Originating from a summer school taught by the authors, this concise treatment includes many of the main results in the area. An introductory chapter describes the fundamental results on linear algebraic groups, culminating in the classification of semisimple groups. The second chapter introduces more specialized topics in the subgroup structure of semisimple groups, and describes the classification of the maximal subgroups of the simple algebraic groups. The authors then systematically develop the subgroup structure of finite groups of Lie type as a consequence of the structural results on algebraic groups. This approach will help students to understand the relationship between these two classes of groups. The book covers many topics that are central to the subject, but missing from existing textbooks. The authors provide numerous instructive exercises and examples for those who are learning the subject as well as more advanced topics for research students working in related areas."
