I had a quote made for the simple board at the qty 1000 it was a very simple 4 layer board. With some passives, some 1.27 pitch connectors M3 LPC, uSD card socket, usb connector.
If I disregard the other components the 1000pcs od said LPC were 22€!!! whereas we can get it in EU for approximately 6€. and asking an EU assembly house would probably get it for even less.
