seeed studio does 4-layer PCBs!

Hooray.  These guys have made PCBs for untold numbers of fpga miners, including all of mine and at least some of rph's.  Now they offer 4-layer boards:

Seeed has unbeatable capabilities and pricing for small runs of PCBs.  If you only want 10 of something they're hard to beat (just don't expect any hand-holding).

They fundamentally changed my approach to making PCBs; experimenting is so cheap that at one point I was sending out a board design every 3-4 days, with up to five designs "in the pipeline".  When it only costs $10-$20 to try something instead of $100-$200 you start to look at development differently.

Thanks for sharing, will use their service someday with such good prices.
It's so great that multilayered PCB's starts to be very affordable for DIY'ers.

Before you get all hot and sticky...
Just take a look at the drill accuracy...and the "punch thru" of the pads.....

$90 for 10 4"x4" 4 layer boards is pretty stellar. I generally use Advance Circuits as they do great work and I pretty much get a stencil with everything, but if you're making a 4 layer at home it's pretty tough to beat that price.

I hate rezzing old threads from the dead, but...

Anyone smarter than I ever looked into using them for Klondike 16 or 64 boards?

Mhm. They aren't competitive with high volume.

Wow,
   Thanks for sharing. Definitely give it a try for the Avalon Quarter Stick prototype.
Hopefully it will be ready in the next few days.
