There's a few small parts that Cels has that I can't find elsewhere, like the smaller secondary spring on the chain tensioner arm, rear brake drum actuating arm spring, side stand spring. Also his mk2 seat looks more authentic than others with regards to the clover within the 'O'ssa, I'm a bit fussy. His parts are also well priced which I felt would slightly negate the expected high shipping costs.
I have bought some stuff from in motion before, their shipping to Australia was very quick and expensive. I've also had prompt service from france trial classic and ossa world in the states, ossa worlds shipping rates to Oz are crazy expensive.
