Looking for smaller 1/2 ID ball bearing

[sanddrag]

I'm looking for a 1/2" ID ball bearing that is either smaller in diameter or width or preferably both than the standard width of .25 and standard diameter of 1.125. If the width is .25, it needs to have a flange (and flange need not be included in the .25 of width). If the width is less (preferable), it doesn't need the flange.

I don't want to use a bushing and I have already checked all the usual places.

I know such a thing must exist, I'm just hoping someone can find it because I couldn't.

Either:

-a diameter of .875 and a width of .25 and a flange
-or a larger diameter and width of .188 and no flange

would be ideal.

And I'm not looking to go for something at more than $10 apiece but if you find something that is more, I'll still take a look at it.

EDIT: I found these http://www2.towerhobbies.com/cgi-bin...?&I=LXD097&P=7 which are the right price but I think they are a little too small.
