We use Google Translate where I work for a some very small customer service related tasks. Our business is not "built on" Google Translate (and has nothing to do with translation), but it solves some small problems for us and is easily worth $10-20 a month for a low volume of requests. Actually, since we already have it integrated and are happy with it, we'd probably pay more just to have the problems solved so we can focus on really important things.
