Apparently there is something odd ball about that particular bearing.
A bearing like that should be no more than $10-$15 ea retail.
It may be a larger O.D. or a different width may be more standard.
Maybe shields instead of seals, etc., may get you to a standard price
bearing. You will need to talk to a good salesman at a bearing supplier
to get similar bearings and prices. Just tell them the ID, OD, and width
you need and that it needs to be sealed or at least shielded.
