Perkins,
This is truly a dilemma. Don't know what to tell you. Apparently, Amazon UK is ordering the book from Amazon US. I think you should stick with that. The first book is very good on the grid layout, as is the new one. The new book, however, will cost you double the price of the old one by the time we figure out how to ship it to Ireland. It costs over $5 to airmail the book across the line to Canada (which we do all the time). No tellin' what they'll charge to get it across the pond.
I think I'd stand pat on the deal.
