Excuse me for jumping in so very late to this thread, but I just wanted to put up a little defence for Irish Safaris. That's run by the shop that I bought my lovely commuter bike and they provided an excellent sales & after-sales service.
Can I ask - did you just email them, and not phone? As someone who will always prefer to dash off an email, rather than pick up the phone, I am frequently disappointed in receiving replies till I make the call.
Hope you have a wonderful time in Ireland, and if you have any questions for an Irish woman, I'll do my best to write back!
