I would go with the OEM clutch, unless you are doing some serious drag racing with slicks and over 800 hp.
Buying of ebay is cheaper but not always better, if you have a problem with it.
I just bought one from Roe Racing for $270 and includes everything: Complete Clutch Replacement Kit:
Complete original equipment clutch assembly, includes pressure plate, friction disc, throw-out bearing, pilot bearing and installation tool.
If you've got the cash, get a B&M Ripper shifter and Aluminum flywheel and get it installed while the tranny is dropped down for the new clutch. Thats what I am doing.
