For my own, all informations about ENCs charts, catalogue, where and how to buy, are collected on the [url=http://www.ohi.shom.fr/]IHO website .
However, the distributors are only for commercial marine, and no way by the time for leasure mariners.
For europe, two main providers :
http://www.ic-enc.org/
http://www.primar-stavanger.org/
And each has its own distributors network.
It's not really easy for us, may be it will change :wink:

For a complete overview about ENCs charts, you may download these two PDFs :
