What ISA cards work with AMIGAs?

[SamOS39]

As part of my A500T project im starting work on schematics for building an expansion board with zorro2 slots.
Looking at pictures around the web etc.. i can see that ISA bus boards look fairly simple.

But is it worth having ISA slots?

What ISA cards (graphics, sound, ethernet .. etc) work with the amiga?

cheers

so the isa slots are only used with emulator cards etc..?

that sucks, ISA cards are cheaper than zorro cards  :-(
