Looking for CDI unit for 200hp

[CCSGB]

Are there any "good" after market CDI units available for a 1993 Yamaha outboard or a parts house that I can get one cheaper than $500.00 from Yamaha?

CCSGB,
Go to ebay.com and type in "yamaha outboard" - I have seen a lot of parts listed there, including CDI units.
Good luck,
