Answer 1

They all seem pretty comparable.  Of course, the more you spend, the better it should be.

Find one at a good price, and make sure that you get a large air tank.  My recommendation would be at least 2 gallons.

As far as the decibels, the ratings are at a ridiculously close distance.  From a car-length away, 120-130dB is probably realistic, if you can maintain 150 PSI of air pressure.
