Clutch replacement. dealer or private Mechanic?

[jambo101]

Theres no clutch slip in normal driving conditions,and i would rather not rev the hell out of the car trying to see if i can make it slip.
The shudder pulling away from a stop is recent and as i have been driving this car daily since i bought it new 8 years ago i'm suspecting something mechanical is wearing out and not my driving technique.
The dealer i'm thinking of taking the car to is Spinelli in Lachine, i have bought 2 cars from this place over the last 10 years and have had no problems dealing with them.
My reason for favoring the dealer is they will have the parts needed will have prior experience in doing such a job and will do the job according to factory standards,whereas my private mechanic while good and trustworthy will be doing a Yaris clutch exchange for the first time,will have to order all needed parts and will obviously not have any prior experience with this job.
