That's for 2 layers, plated holes, soldermask and silkscreen on top and bottom. I think most of them claim <8 mil trace and space, but I wouldn't press the limits too much if you don't have to. They also route to whatever shape you'd like (rounded corners, a round board, whatever). Some of them offer colors other than green at no additional charge.
I've had excellent results. I did have one board that was mis-drilled (somehow, four 8mm non-plated holes from one board got copied to another) but they remade it without question.
Here's an example of a board that was $15 for 10 copies from Elecrow.
