Whats the cheapest place you've found to do this?
Hope this isn't too far off-topic,

Sierra proto express: (USA)
http://sierraprotoexpress.com
2 boards up to 80 square inches for $121 with mask and silkscreen. I
have not used them yet, but they have been quite responsive to my
questions. 6 mil track and space. The minimum via is 15 mils with is a
bit large. They will not make arrays of boards.
I will be using PCB Train (http://pcbtrain.com) for my next board since
the sierra proto express vias would not fit between the pads of a 1mm
pitch BGA. They have also answered a few of my questions quickly. They
seem willing to do arrays of boards. I like this since I am working on
3 different credit card sized boards and can save money by combining
them. I will let the list know how this goes.
I have used PCBExpress before and they did a good job, but are about
twice as expensive as the 2 I mentioned.
