I can get 5 from Germany for ~=E2=82=AC115 and even ~=E2=82=AC10= 0 with a=20 savings (9WD instead of 5) option. That's with 0.2mm PTH and 100=C2=B5m track/space. Not very aggressive in terms of drill size, but rather fine line etching. And yes, I've used them for 2, 4, and 6 layer boards. By default 2 layers are HAL lead-free, 4 and more are ENIG. Even with 8 layers, 5 boards of that size are ~=E2=82=AC200. Price explod= es when you go to 10 layers (really ~=E2=82=AC500).=20 Gabriel (soon going to spend much more on a 4 layer design, 100x160mm, but=20 external layers are 4 mil thick RF dielectric for broadband analog=20 signals up to ~20GHz)
