I could have sworn I posted a reply to this yesterday asking the same question...
If you used the one piece master/hose/slave it's pre-filled with fluid and pre-bled, you just install, step on the clutch and top off the fluid.
This setup runs $130 or so if I recall.
I have an OEM replacement plastic reservoir master with a stainless braided hose from Advance Adapters and I bought one of their AX15/NV3550 external slaves. If you do end up needing a hose, I recommend the AA one it feels really good and consistent, the braided stainless cuts down on the spongy feel a bit. Same with brake hoses. -- The 42 or 48 or whatever inch hose they sell is barely long enough, it's what I used and I wish I either had a 180* brake line fitting on the end to sweep back into the clutch slave, or that I'd gotten their 60 inch hose kit and had a sweeping bend instead of having a taught hose.
Note, a 3-piece system is harder to bleed, especially when the slave doesn't have a bleeder port. You can either use a vacuum bleeder at the top to suck the air bubbles out or bench bleed it really friggin good before installing and don't shake it around/tilt it.
