There was a thread a few years back discussing PCB proto services, perhaps it is time to revisit.
I would like to hear about any user experiences, including things like price, quality, turn-around time, shipping costs and so on. I have found a few so far:
http://oshpark.com/
* USD5 per square inch, for 3 copies. Flat mailer is USD8 worldwide, shipping from US. Directly parses EAGLE files and quality looks high (ENIG).
http://www.elecrow.com/
* 5cm * 5cm USD9.9 / 5cm * 10cm USD23.9 / 10cm * 10cm USD23.9, 10 copies. ENIG more expensive, but you can choose a PCB colour for free.

* Basically the same pricing structure as above, more for colours

* Again, similar pricing structure (5*5 cm USD10, 10*10 cm USD25). Free shipping is available for orders over $50, you can combine with components or Arduino etc.
