It would depend on what kind of equipment they are using, and the quality of their work. Prices sound ok, but without seeing their work I couldn't say anything about it's value..... For example, cylinder honing. A shop here in town uses and old hone with stones on an electric drill motor. Race shop we use has a computer controlled power stroke hone and uses deck plates on the block when they bore and hone the block. As you would expect, the labor at the race shop is about twice as high, but usually the rings are seated by the time it comes off the run in stand.
