personally i haven't been very happy with advanced circuits, but i don't
want to bash them at this time
I have used Imagineering for some double sided stuff and had a few
shorts (much like elsewhere, but did not order test)
I will say in their favor that on several orders their delivery time was
exactly as quoted and was pretty quick for no premium charge
but like you (but at yet another shop) i ordered AND PAID for elec test,
and the 5 out of 100 bds had bad shorts
when I called they looked into it and said that there was no test
i pointed out that I ordered test and they billed for test
so much for them, but i did at least recover the test fee
