Only one or two I looked at offered an online quote tool, and none of them came even close to the usability and functionality of PCBWay's website. The best one I found was this ridiculously overbuilt system with an embedded 3D engine and one of those shitty 200MB web apps that take 30 seconds to register a click and breaks your back button.
USA is simply not competitive with China on PCBs. For small, cash strapped business, domestic manufacture has never been an option. I expect prices will only go up and up as our entire domestic capacity is absorbed by big corps that can afford the premium. I have no idea how us little guys are supposed to get boards now.
