[LAU] audacity alternative?

[Greg]

Hi all, I was wondering if you knew of a good alternative to Audacity.
 For whatever reason I just don't like it.  What is a fast, solid
sample editor?  I liked mhwavedit but gave up on it because it seemed
to unstable.
Basically something like an Ardour jr. would be perfect.  Is anybody
using SND for this purpose?  It's got a high learning curve and I have
not seen much written about it online.
