Even if they don't deliver to Ireland, if you have a friend in the 6 counties, I'm pretty sure you could get it delivered there. Have a look at their website:
Anoher of their bikes worth a look is their Revolution Cross at £450. It's a crosser but has all the fittings you need for touring such as rack and mudguard mounts. In fact, it uses the same frame as one of their tourers. For £600 you could have a pretty good tourer, I know, I have one myself and the oe cross tyres work very well on the road.
