I just bought a new Exedy/Diaken for my '98 EX (mine was slipping at 101k miles) for about $115 shipped from here.

That low price made me nervous too (includes disk, pressure plate, pilot, throwout bearing and alignment tool) but I've had it for about 2000 miles so far and no problems yet. The stock Honda clutch disk I pulled out was a Diaken too. Cost me $40 get the flywheel cut and I was good to go.
