I'd second that.  Having experimented a lot, ProjectX has been the
only 100% reliable tool I've used.

I don't find it too bad.  It could be quicker, but once you've learned
the keyboard short cuts for the 4 different skip lengths, its quick
enough to find the cut points.  Its reasonably fast at actually doing
the demuxing too.  I run it on an NFS mount so I'm not expecting much,
but it maxes out my 100 mbit network usually.

I can't say I've seen any artifacts in the >100 disks I've made!

If you have a really spotty recording then the gaps in the audio
stream can get disconcerting, but that is hardly ProjectX's fault.
(You can fill with the previous sample which works well for small
gaps, but for big gaps it is really wierd!)
