favorite board houses for more complicated boards?

[Michael]

Hey there - I typically use Advanced Circuits or Sunstone Circuits for
my PCB manufacturing. Their prices are decent and their turn around
time is good.

Anyways - they both have very limited capabilities. For fancier stuff
they always say that they can't do it or that they'll have to have it
done by somebody else. I just can't imagine it's cost effective to use
them as a go between for another board house.

So, specifically, what I've wanted to do that they have not been cable
of is filled vias, capped vias, and extra thick copper. Can anybody
recommend a board house that can do these things?

Thanks!
