Just view the inventory for the Dimensions - they're required to rebuild those when people return them, so they're really not any different from new ones and they're MUCH cheaper. Mine's going on 5 years. Oh wait...they may not be able to ship to Ireland...not sure really. Maybe there's a European version?
