I've never actually used them but their online tooling is impressive, they have reasonable prices for low quantity assembly, and they've manufactured and fulfilled a few kickstarter projects.

Hi there! I am the founder of MacroFab, and I'm happy to answer any questions. Quick summary though: we do US-based (in Houston, TX) assembly, we offer low-cost prototyping options along with production quantities all with real-time quoting down to the component level, build-box assembly, programming, testing, inventorying, and fulfillment. We have APIs to allow direct integration and we have a number of integration partners coming online this year.
