I can second the Doras range. We got 12 of the oak ones with frosted glass, from O'Halloran Joinery in Cork.
One thing though, the doors may be €200, but the ironmongery, (handles, scutchens (sp?), locks, hinges etc. will set you back another €200~250. Also factor in the frames, arcatraves and skirtings.
If you go with wooden doors, you will probably go for wooden arcatraves and skirting.
Factor in about €75 per frame, and same again for arcatraves. Oak skirting was €3 per foot.
Worked out about €500 per door for us.
