I think crushed malt will suit most of us as I don't know of anyone who has a crusher. The only factor with pre-crushed grain is it doesn't keep for as long but it still has a reasonable shelf life. Storage for hops & yeast is important though as they need to kept cool (yeast) and ideally frozen (hops) - is this something that will be possible for you? (not that I'm suggesting the other Irish homebrew shops do this, I really don't know. I believe the likes of Hop & Grape do and a lot of us order small stuff like hops and yeast from them)
