Where should I go to get my car fixed?

I have a 2007 Ford Focus SE and my MAS (map air flow) is bad. Engine idles too much and I'm burning gas twice as fast. I took it to one mechanic and he diagnosed that I needed a brand new one. For him to do it is 360$. I did so research and found another mechanic that's willing to do it for 200$, but he said there's no warranty on it and doesn't guarantee it will fix the problem because he hasn't seen it yet. I know it's a faulty MAS but should I go the first guy with the 360$ with a warranty or the second guy 200$ without a warranty? Need to know by Friday because I have scheduled appointments. Just trying to save some money, Thank you!

2000 Ford Focus Slow Acceleration and Pulsating at Stops?

I have already replaced spark plugs and wires and I suspect that it is the Ignition Coil that is the problem.
The check engine light is constantly on and begins to flash on occasion while accelerating.

Could it be anything else other than the ignition coil? I'm a poor college grad and can't afford a new car at this moment or dumping money in "fixes" that don't fix the problem.

I'm a semi-novice so explanations would be great.

It has a 2.0L, 4 cyl engine.

Added (1). The spark plugs and wires were definitely in need of a replacement.
