Hej
Here in Finland the SC brand is common due to the high prices on everything.
I order my OS engines a Tower Hobbies and pay 22% VAT + ~$30 in shipping...Still comes out cheaper than buying an OS locally.

If I were you I'd try to get an OS or Saito from USA, it's about the same cost and you get a great quality engine.
...I really don't have much experience with the China made engines, but I rather pay more to get a well known, Made in Japan quality brand.

...Did I say I like OS?
