Not used Pooleys or AFE for some years, but Bottlang allows you to specify which countries you want. They do "batches", depending on your preferences.
I have the UK/Ireland/France/Benelux version which suits me fine.
You can get the Isle of Man plates - all of them, including the ILS etc, at
http://www.ais.org.uk/uk_aip/pdf/ad/EGNS.htm
which is an address to keep well bookmarked!
