Where is the best place to register a .ie domain name?

[Juniper]

I am looking to start a non-profit making site for my wife's family, both the .co.uk and the .ie domains are available and whilst the .co.uk is obviously less expensive, I feel that the .ie name would sit better with the older members of the family.

Registering the domain should not be an issue, (many of the family live in Ireland and one of them would be used as the contact.) so I was wondering if anyone could point me in the direction of the best place to register a .ie domain.

Obviously for a 'not for profit' site, the cost of the domain is an issue.

Thanks
