I'm going to build a hobby CNC machine, so I really need to know where selling Aluminum Extrusion like this:

It easy to find out a online shop at US or UK, but the shipping cost and VAT is crazy, 5-10 times higher than its cost. (because it really long so the shipping cost is hiked)
But in Helsinki, I don't know where to buy.
If anyone knows, please let me know, I can buy a cup of coffee for you in a return

Or if you are interested in same hobby, we can discuss more in future

Thank you very much!
