When it's all said and done, a clutch slave cylinder is about as basic as it gets. There is likely zero practical benefit from a pricey multi colored anodized pice over the $25 Napa replacement, it's a bore, piston, spring and rubber seal.
Get the Napa replacement..... about a 15-20 minute job counting readjusting the pushrod.
For 1/2 that, go with a little sandpaper in the bore and a new seal.
