You can get Deanta pre hung door kits in Donegal for 270 euro each...thats what I opted for and was happy with that...I believe you can get the Oak door for 99 euro from the same supplier.
Door will come pre finished and varnished in door frame inc handle etc and architrave to be fitted...fitting from my supplier cost 60 euro though I already had a carpenter for the job and did not engage him. Wish I hadnt as he's now trying to charge me a fitting fee of 200 euro per door.The whole point of the exercise is that it should be a quicker job as the bulk of the work has already been done.
