Fuji S602 - Sugestions for wide angle add on lens??

[Snowdrggn]

I'm using a Fuji S602 Pro, I would like to purchase a wide angle convertor for it. I already own the Fuji Telephoto adapter, and 55mm x 55mm adapter tube. Could anybody offer suggestions, or the pros and cons of the Fuji vs Olympus add on lenses? I am not interested in inferior add ons, only the better quality ones.

Thanks,
Snow.
