I spent about $250 for parts, Timing Belt, H2O pump, spark plugs and the 2 belts - Serp and Timing.
I too was slow and 2 days was my goal - then I had to deal with a sripped bolt and was very careful getting it out so that took some time.
Do not, I repeat, Do not try to replace the tensioner on without compressing it or better yet, get a new one. And go through everything in the manual and get all the nuts and bolts with a Black Diamond indicator - non-reusable.
