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.
