There is no such thing as cheap OEM plastics........
Co-sign. I spent abot 8 hours on saturday on the net looking and this is the cheapest for OEM parts that I found besides Ebay.Pretty reasonable prices, 30% discount from OEM prices.

I just ordered the undertail ($65), uppertail ($140), grip assembly/throttle tube ($14) and a few screws I lost for $235. I went to the dealer to get quotes and they priced me at $326 w/tax.
