Didn't get any negative feed back on the translations in Spanish, German, and Japanese.

That doesn't necessarily mean they're good translations. As a webmaster and as a user, I would never do business with a website that machine-translates its content (or ads). Wouldn't link to it, wouldn't buy from it, wouldn't like it, would be a little insulted, would remember it, would press the back button and block the site from search results.

Of course, Google is just as good at catching machine-translated language as any near-native speaker. If all of this doesn't apply to what you're planning on doing, however, then by all means give Google Translate a go. The amount of language data they have at their disposal is immense and rapidly growing, at the same time maturing the quality of their translation service.
