Hi Iain!
You've just taken the first-best step toward owning a second-hand Thorn bike of your dreams by posting your "wanted" announcement; well done, and good luck! This is an excellent way to find what you want among enthusiasts who can readily advise you and are likely to respond.
To better your chances further, may I also suggest keeping an eye on this Forum's Bikes For Sale Board:
http://www.thorncycles.co.uk/forums/index.php?board=16.0Please don't neglect SJS Cycles as a possible source. They often make available used, returned, overstocked, or shop-demo Thorn bicycles at sizable discounts. If the bikes are listed as new, they will often specify a new-bike warranty; used models will not carry a warranty, of course. To see the available listings, go here:
http://www.sjscycles.co.uk/clearance-zone-dept756_pg1/Both SJS Cycles and Thorn maintain Facebook pages, and good bargains often appear there, only to be snapped up quickly by an eager audience. To see these pages, go to:

https://www.facebook.com/TouringbikesDealing with Forum members or SJSC/Thorn avoids many problems, but there are other venues where you can find Thorn bikes if you exercise the usual cautions. Gumtree is one (
http://www.gumtree.com/ ), Donedeal in Ireland is another (
http://www.donedeal.ie/donedeal/ ), and the United Kingdom's home version of eBay is also a rich source. Just go to ebay.co.uk and enter the search string, "Thorn Bike" (no quotes) and you'll see the listings. For your convenience, I have made a customized search link available here:
http://www.ebay.co.uk/sch/i.html?_trksid=p5197.m570.l1313&_nkw=thorn+bike&_sacat=0SJS Cycles has its own eBay page where accessories, components, and occasionally bicycles are listed:

Welcome to the Forum; you'll find a pleasant and generous community of enthusiasts here, all willing to help answer your questions.
Best,
Dan.
