I would advise against getting maier plastics. I hear they don't line up correctly, and they are flimsy compared to OEM. Plus, they'll cost you +$600. I'd check e-bay or Craigslist for a nice set of used plastics.
To tell you the truth....By the sound of things, you may come out cheaper buying a complete quad.
If you lend somebody $20 and they never come back, then it was worth it.
