How much for control arm shaft/ball joint replacement?

[LowGT]

Ok, I'm converting to front disc and installing a complete front/rear suspension rebuild kit. I removed the upper and lower control arms and cleaned them up, man I had to go after some of that stuff with a chisel and hammer!

I removed the upper control arm shafts/bushings. Now I'm taking all the control arms to a shop to have them:

-Remove factory upper ball joints
-Remove lower ball joints
-Remove lower shafts/bushings

-Install upper ball joints
-Install upper shafts/bushings
-Install lower ball joints
-Install lower shafts/bushings

I haven't had much luck with machine shops in the past as far as work quality and knowledge go, so I took it to a place that does complete car restorations all in house. I talked to the owner, he claims to be a suspension guy. (drives a 55 pickup tall enough for the bumper to hit me in the chest) Anyway, he had a 67 in the shop already and had all the right responses with measuring and centering the shafts, etc... so I felt good about his knowledge of the work to be done. He quoted me $400 to do everything listed above, and my initial feeling was that was expensive, but I have never had stuff like this done before so I just don't know.

Is $400 too much? Good deal? Or about what you would expect?
