Yup.. +1 on Laen/DorkbotPDX and iTeadStudio.
I use Laen when I'm still working out a design, and then iTeadStudio when it's ready for larger quantity. You can't beat Laen's quality and service. Likewise, iTeadStudio's price is hard to beat, at <$1 per board at 5cm x 5cm.
Next month we're going to try out Laen's "medium run" order, which is $1/sqin with a min of 150sqin. That's not phenomenally better than the usual price of $1.66/sqin/board, but the boards look really nice so we shall try it.
