Costs of Nested Tables

I was hoping somebody could shed some light on this issue for me...

What additional costs are associated with using Nested Tables in Oracle - as opposed to using multiple separate tables. i.e., Instead of having 10,000 tables, have one table with 10,000 rows where each row contains a nested table. (and each of the 10,000 tables might have 100-20,000 rows).

Can somebody give me some pointers as to what costs this will impose, and if this is good design?

Any help is very much appreciated.

Thanks,
