Got my PCB’s back from PCBWAY, they were very nice! They offer right now $5 off once you sign up. 10x10cm are normally only $10, that’s $5 with the signup offer China PCB Prototype & Fabrication Manufacturer - PCB Prototype the Easy Way PCB colors are almost all free also… They offer a very nice online quote system and order tracking, one of the better I have seen, and the boards only took 6 days to get here! (I used DHL) Let me know if you use them and how you fine it. Perfect for of course esp8266 designs and any arduino type boards you might make… (I think I also saw free Vero-type PCB boards that you can add to your order for free)
that’s QTY 10 
How much shipment costs?
Minimum order of 100 boards?
How do the boards compare with oshpark?
The cheapest shipping I found was 10 USD to Europe.
PS. I haven’t tried them, I just looked at price since it seemed fairly cheap.
Yeah its very reasonable…
You can order as low as 5, but same price as 10
With regards to OSHPARK, I find them very good, but once you go over just a very small board the prices are just too much (for me) and the Chinese are now making very good PCB so I find it very good to use PCBWAY.
