TransferWise has a robust "no bovine manure" approach. I've used different kinds of services from them over four years, and they have been consistently excellent. I make sure to tell so whenever I talk to them, and politely make a note to not lose sight of the valuable things that customers are happy about (transparency, competent human support).

And I like it that they charge a decent price. I have a general allergy to "gratis services", especially in finance-related things.
