IMHO - if you want a really good read, join (the original USA) AOPA and get their magazine. Far, far better than the UK competition and with the dollar where it is international membership costs the same as - or possibly slightly less than - a one-year P*lot sub. The UK AOPA mag is also good, but sadly it's also got less content and membership is a lot more expensive...
I do subscribe to both Flyer and Pilot, although i'm increasingly wondering why - especially with Pilot. I agree with Mr. Wolfie, I'm fed up with reading reviews of the same aeroplane/course/whatever in both. Flyer at least has John F and Irv.
Edit: while i'm on my soapbox, i'm fed up with fuggin' articles about flying from here to bogdovia. Took off. Landed. Had lunch. Put fuel in aeroplane. Took off. Landed. Bit overcast. Had lunch. Repeat for four pages... it's good cheap filler from someone who took a few pictures, but it's no use to anybody and oh so dull...
