Which ever Guide you buy I would advise taking up the amendment service.
If you, like so many private pilots, make it last more than a year you will eventually have unreliable info. Sure phoning for PPR will often ellicit relevant info and the obligatory NOTAM check should reveal WIP etc.
But think of your shiny new book in Aug 2003. Eight months will have elapsed since it was printed, Will the AFISO you call remember the new mast just outside the ATZ they put up in February?. It won't show in the NOTAMS after 6 months and as you impress you pax by scud running in you may get a nasty surprise!
I've used Bottlang in lose leaf format with the amendment service for many years and am more than satisfied with it.
