Hi Dunc and welcome to the Thorn Cycling Forum!
I have an idea these remarks will mean more than you can imagine. Sales and service is often a thankless job, with people in general far more likely to complain than give praise.
Not only will this make some days a little brighter and give credit where due, it will help Thorn/SJS Cycles, who kindly provide this Forum for all of us to discuss their bikes, touring, and all we do.
Robin Thorn and Andy Blance provided outstanding customer service in my own time of need, and proved they are as good as their word -- and even better -- on warranty issues both minor and major.
Here, here! Thanks for the very thoughtful post, Dunc. Very best of luck in the difficult selection choice ahead -- what a wonderful dilemma! I'm sure you'll also find ample help here among our Forum members as questions arise.
Best,
Dan.
