New Clutch dilemma

Lionheart

I have a '13 z with 41k miles on it.

The slave cylinder crapped out a couple weeks ago. Initially thought it was the clutch so had a friends shop look at it, but once I learned it was the slave cylinder I sought to get the powertrain warranty to cover it. The dealership said the CSC was NOT covered by the powertrain (!). After a persuasive chat with Nissan consumer affairs and some waiting Nissan agreed to cover the cost of the CSC.

When the dealership service center removed the transmission they sent photos of the clutch and it is pretty worn. Dealership wanted 700 for the new clutch system and 1200 for the new flywheel to replace in parts alone. Will not resurface the flywheel. Fortunately, since the labor is covered by the CSC replacement agreement, the labor charge is minimal to replace the clutch/flywheel.

$2000 to replace the clutch is more than I want to pay out of pocket. So here's my dilemma:
1) replace the clutch WITHOUT replacing the flywheel using genuine Nissan OEM clutch (cost $800 w/ labor).
2) Buy Stillen clutch + flywheel kit ($1000) (or another third party brand) and have the dealership install that for just labor ($150) [Total cost = $1150].

I don't track the car; it's my daily driver. Which makes more sense? Is a new flywheel really necessary? What would you do? If you suggest replace the complete clutch + flywheel assembly, which brand do you recommend at around the $1k level?
