650 is very reasonable!
I paid a vw dealer tech to do mine on the side (at the dealer still, just his day off) and I paid 500 for the labor including him installing a front sway bar and doing an alignment and sensor calibration… 6 months later when I destroyed that clutch he charged me the same to do the job again , and 5 months after that when the DKM TOB decided to goes and cover my clutch with fluid - I figured it was time to save a little and do it myself ( its a highly unpleasant single man diy )
I'm debating whether to pay someone or do it myself. Did you use a youtube guide to do it?
