I prefer Newegg over Amazon because of their return policy and customer service. I could be bias though because I live about a hour away from a Newegg warehouse. Newegg also has a better review system with educated users.
As for the HD, is transfer speed a concern? If so, you might want to decide if you want to transfer using USB(2.0) or the 1394(Firewire) port on your laptop. Something like the Fantom Drive has Firewire 400/800/USB2.0/USB3.0 and even eSATA at 136$ US.
:;Edit:: Their international site can be found at http://www.newegg.com/global/ie and from what I can tell, they still ship to Ireland. Just watch out for taxes.
