In PCB I will look at the soldermask clearance.
I will also very the drill sizes using the drill report.

I always look at the gerber files with gerbv. Copper clearance.
Silkscreen over pads.

PCB Express is cost effective for very small boards or very large boards.
If you panelize the boards yourself there is no charge. I just ordered two
panels from PCB Express that had a three different designs.
Each panel, < 9in^2,  has  2 2in^2 boards, 1 2in^2 boards and 2 1in^2
boards. The total was $160 dollars SM + SS on both sides
(2 day lead time) next day air. For another $100 you can get a one
day lead time (I used this twice in the last month ;)

If a single panel was > 9in^2 I would have probably gone with Advanced
Circuits.

Both vendors have a high quality process and are easy to deal with.
I would go with either one based on cost and lead time.
