Are there any new sources for Bottom Bracket CUP SET FRENCH 35X1MM 2xRIGHT

I am restoring a crappy french bike I bought for 10 Euros (I currently live in France). Its a "France Sport" mixtie. I am using it as a way to learn how to restore bikes, I hope to work on more and better bikes in the near future.

My current issue is that the bottom bracket cups are pitted, and it just does not seem right after all this work to reuse pitted cups. On the other hand I don't want to put too much money into it.

I have searched somewhat and have found the following;

-- Harris Cyclery for $20; http://sheldonbrown.com/harris/frenc...s.html#bottom2
-- Amazon, looks like exactly the same product as Harris, but for $10; http://www.amazon.com/Bottom-Bracket.../dp/B003ZKOOMC

Are there any other sources? I would like to stock up, but would like to pay less that $10 per set (otherwise, I am likely to just pack the existing set in grease, and hope for the best).

Thanks for your help,
Bruce.
