Spa Cycles do an excellent low cost version of this chainset for £35 http://www.spacycles.co.uk/products.php?plid=m2b0s109p2000
Also, cranks only for the bargain price of £20 http://www.spacycles.co.uk/products.php?plid=m2b0s109p2003
Spa wrote to me a couple of years ago that they were sorting out their postage charges to Ireland. Might be worth asking them what they charge now, because basically they sell the same Sugino crank that Stronglight brands for a third of the price. On the other hand, you can buy Stronglight from XX cycles in France who reasonable postage and are a reliable dealer.
http://www.xxcycle.com/road-crankset-and-stronglight,en.phpNote that two types of Sugino cranks are called "Impact". One is the very beautiful Cospea that I have, and the other one I think is called Alpine !! when branded by Sugino. It is the latter that Spa sells.
Sugino name Cospea
Sugino name Alpine II (I think)
I'm just wondering if the cranks that SJS gives you anyway on a Thorn aren't either the same or a pretty good substitute for the Alpine II.

I have aluminium Stronglight chainrings off these cranks, brand new, never used, five arm, 110 PCD, 48T and 38T.
These cranks come with either ali or steel chainrings. The steel cranksets are much cheaper. If my rings suit your gearing... If you can find a crank that otherwise suits but has steel rings, and my chainrings are any good to you, you can have them free of charge.
