audio editor thoughts? Anyone?

[cmh at chariot.net.au]

Hi 

I am testing out some mac audio editors. Are there any thoughts/experiences 
on mid-price audio editors which could help on a decision? The later 2 seem 
to have better processing options where as the first seems to have more core 
editing features 

I am currently testing
1) peak le
2) spark le
3) dsp quattro 

This is for a lab setup which currently has peak le 2.6 running. We are 
considering an upgrade to peak le3(4) however the upgrade would cost about 
the same as buying a new editor from the other companies (hence the option 
is open) 

Cheers
C.
