If you buy a new flywheel, I would go with a one that has a replacable friction surface. Also look around for a local clutch company near you. I have one near me called Ky Clutch. All they do is rebuild clutches, and you can usually score a pretty good deal. I talked to the owner and we kinda mixed and matched components for my needs. Best thing is be honest about your intended usage and power output if you go this route. I think i had all of 250 dollars in my clutch setup, that replaced a centerforce daul friction unit that costed hundreds more. I ended up with a pressure plate that has the clamp load of a stage 4 clutch and a 6 puck sprung hub disc that is daul friction material. Holds great, but it has some drawbacks also such as wearing out your leg and alot of chatter if you try slipping the clutch in traffic. When i say chatter, i mean that it feels like it wants to break something when slipped, thats how grabby it is. I either have it all in or all out, and no slow releasing it. But I was well aware of this and the owner also advised me of how it was going to act before i bought it. I will say the centerforce had great manners though. Easy pedal and no chatter at all. When I took it out, it had lots of material left, but it was glazed over severly from slipping when the boost started rising.
