[EX Q]: A wonderful pictorial book about transistor radios, 175 of them, not only photographed but put in the context of fifties and sixties design. The spread on 60-61 shows six radios mixed with close-up photos of chrome styling from fifties cars. I loved the chapter on design with its photos of grills and lettering, even a spread on 9-volt batteries.This is the kind of book that Chronicle do so well, interesting subjct, well designed and printed all for the general reader. If you collect these radios you will certainly want to have a copy but don't expect to get lots of technical detail or a price guide. For that have a look at 'Collector's Guide to Transistor Radios' by Marty and Sue Bunis, plenty of text about seven hundred models, some photos and that all-important identification and price information.
[EX A]: Positive

[EX Q]: Only has limited access to OBDII data stream unless you pay more money to upgrade the software.
[EX A]: Negative

[EX Q]: The motion picture soundtrack, yet alone the motion picture of EVITA, is terrible. Hollywood, as usual, took a wondeful piece of work (the hit musical EVITA) and butchered it to be their way. Patti LuPone is a far better Eva than Madonna, and at least you can understand Mandy Patinkin, unlike Antonio Banderos. Also, Hollywood turned the orchestrations into modern rock 'n' roll junk, when the 1979 Premiere American Recording is the way EVITA should be. So don't waste your money on the movie sountrack, and buy the Premiere American Recording instead
