Agreed, if you look enough and patient, you will find great deals on plastics! That is how I rebuilt my damaged 6 afew month back.
Saved me $1500 over plastics alone compared to getting them the Yamaha Dealership at wholesale prices!
Try this place. They offer OEM painted plastic for way cheaper. To replace the right side faring on my wifes 03 GSXR 600 it only cost around $400. E-Bay is good too but the people on there go crazy. I have seen the same used slightly damaged faring for the GSXR go for 500 - 700 dollars. Moto-Xtreme is brand new OEM and painted. Check it out. When you get to the website you have to E-mail them a decription of what you want and then they will e-mail you a price. It is totally easy. They also carry other Apparel and Accessories!!! Good Luck!
