This is a good discussion and rant.
As a dealer in the USA, I too struggle to understand why Tanos/Festool/Bott don't make the rails easier and more accessible in all regions when this is a keep feature of the Systainer3. I've sold rails in the US and I've shipped orders across the globe too.
I'm happy to quote shipping to your destination, get in touch. And it may be that buying in a bulk with some friends help, I'v had a couple customers do that.
I'd also recommend writing to Festool and Tanos to express your opinion. Let the customer be heard.
