What exactly is your dealership quoting? A front brake job can range from a simple pad change to pads and rotors, to pads, rotors and fluid bleed and/or change. There's no way to know if that price is a deal without knowing the scope of work.
In general, the following rules of thumb apply (though YMMV)... Dealership service depts are notorious for overcharging...they are a major profit center for the dealership and prey on people's fear of getting ripped off by "the other guy". Their mechanics are usually well trained but often not too experienced. Independent mechanics who specialize in just a few makes are best. They usually have expertise, lower prices and experience, and don't have the dealership execs breathing down their necks to up the profit margin. Make sure to get recommendations first (see
http://www.cartalk.com if you don't know where to get any). National chains are in general the worst...low paid mechanics, high pressure to charge for extra services, cheap knock off parts.
Unless the rotor surfaces are glazed or heavily scored, there is seldom any reason to turn them. In fact, rotors these days are much lighter than in the days of yore (i.e. the 70s and before) when there was plenty of metal on them and turning was a frequent rotor renovation method. Oftentimes shops turn them purely for the purpose of making a little more money off the customer. Turning can actually be a bad thing...it makes the rotors thinner, which means they are more susceptible to warping, and some car makers specifically state that their rotors should not be turned. For most cars the sequence should be:
1)check rotor for thickness...if too thin or warped, replace rotors and pads and go to step 3.
2) check for rotor damage...if none, change pads. If scored or glazed determine whether resurfacing is approved by car maker and/or can be done without compromising thickness. If so, turn, replace pads.
3) Check sponginess of pedal. If spongy, fix problem and bleed.
4. Check how long since last brake fluid replacement. If 2 years or more flush and bleed.
