[Amps] off topic -- books recommended

[Chris Howard]

This is off topic...  but maybe not too
offensive in that department.

I received some gift certificates for the ARRL recently.
I'm looking at their technical books.

Do you all have any you particularly find useful?

I have $$ enough to get two of the moderately priced, or
one of the hefty ones.  And I already have the 2006 ARRL Handbook.
I think I'm looking for a "learning" book, not necessarily a reference.
And reprints/compilations of QST/QEX articles really don't do much
for me.  I feel like I already have enough unfinished projects without
getting a bunch more.

In order of interest (so far) I'm looking at:
 
Experimental Methods in RF Design
-- by Wes Hayward, W7ZOI, Rick Campbell, KK7B, and Bob Larkin, W7PUA

Practical Radio Frequency Test & Measurement
-- A Technician's Handbook
by Joseph J. Carr.

ARRL Antenna Book
