I have just subscribed for 1 year to MAGIC magazine after having bought 1 issue to test the water from magictricks.co.uk.
I have found it to be a well presented (some terrible spelling misyakes at times

) and informative magazine. It contains up to date news, columns / routines for childrens entertainers (silly billy writes this one) / restaurant workers / card fanatics as well as articles on the history of magic - magicians. It has many adverts from magic retailers and info on conventions. As it is written in America alot is US based info but it does not leave out international magic.
I haven't tried GENI but am very happy with my subscription so far
