Good sound editors for mac OS10?

[Edward alonzo]

hey all thought I'd just post here to see what you guys thought of  
sound editors.
I was in the windows world, using sound forge, and was looking for a  
similar program for the mac.
Any good Ideas? I've tried sound studio, but, it doesn't seem to be  
like sound forge in that you can't seem to select huge chunks of audio  
using both the left and right brackets there is a marker feature, but,  
ti seems to just be for dropping markers in the file it doesn't seem  
to be a audio marker selector.
Maybe you guys have some ideas on a good editor, or maybe you know how  
to achieve the affect I'm looking for in sound forge.
thanks-for any help.
