Best TV Repair Book?

I've got several of these from the 50's, 60's, some of the Art Margolis books, etc. but few seem to offer many of the helpful 'kinks' that Sams (for example) gave in some of their bulletins, which I suppose, were factory recommendations.
Are there a couple that you've found especially helpful? I see these on eBay all the time for little $$ but I hate to further clutter up things on some bound paper that I'll have little use for.
Suggestions?
Thanks,
Michael
