Have you looked for a supplier of springs and other parts in your part of the world? I'd take it in and see if someone in such an outlet has an unbranded replacement part that will do. Another option might be if you can find the part on ereplacementparts.com, someone here can find a cheap way to get it to you? This looks to be a very commonly used spring. After all, it just has to fit. I tried to look up the part, but need the model number to find it. Perhaps if you can find the part, you can have it delivered to a family member here who can ship it to you. I'd order two and an extra collet at the same time. I love and use my trim router a lot more than I ever thought I would. So easy to handle.
