Ken,
Based on Steve's pricing data above I think the rebuilds are in the same basic $$ class as OEM. Dali does give you the light weight flywheel though, instead of the heavy OEM version.
I also think Mark's offers additional clamping force. Are you going SC or Turbo? I actually think the OEM is plenty strong if the engine is stock or with just H/E/I mods.
My $.02
