If you can find a UK supplier which will make prototype boards for anything like £60, do please let me know. The closest I've found is PCB Train, but last time I used them (Chinese new year) the cost was an order of magnitude higher than AllPCB.
The sad thing is, although I'm sure most of us would happily pay 'a bit' more for a local supplier, 'a bit' isn't an option. Buying small quantity prototype boards locally is stupidly, ridiculously, disproportionately more, and UK suppliers don't even bother to try and compete. I don't blame them; they really don't have a hope given how labour intensive small batch prototypes are.
The irony is that the availability of inexpensive, fast turnaround prototype PCBs from China means that I in turn have been able to offer a similarly fast turnaround, relatively low cost prototype service to my own customers. This last year I've done good business hand assembling the first few samples of various jobs, and delivering working prototypes instead of just CAD data, which would otherwise have been uneconomic for me to do.
Ironically, this means that *more* manufacturing value has remained in the UK, given that the alternative would have been PCB fabrication and assembly in a Chinese factory.
