I think you're spot on Mark....
When I first got my first GSA in 2006 Touratech was the Mecca of the bolt on goodies. I'd spend ages on the stall at bike shows drooling over the products, and flicking through the catalogue.....
....but I've bought Touratech products in the past that I've not even bothered to fit to the bike because of the poor quality, or poor fit of it. I don't think they've improved, and I don't really look to buy anything from them much anymore.
I find the wunderlich products much better...and of course your items, which just ooze quality.
I agree that with the resources at their disposal they should be able to balance quality, with production, and good customer service....sometimes I think they've been No1 for so long that they think it's their right.
Anyway....like you say this isn't a Touratech beating thread, but an impressive thread by somebody doing it right
