Where is a good place to buy bearing for my Shimano Scorpion?  I would like to get some really nice ones, but if cost is over $40 I will stick to factory ones.

Boca Bearings, Smooth Drags, or VBX has them.  Prices range from $15 to $80 depending on the style and ABEC rating.  You want ABEC 5 or better.  Should be less than $20.

You will need a couple of 3x10x4mm for cast control and palming side spool support...
