I use Sonar now more than anything else, but Cool edit is a very nice program, except the multitrack version is pricier than the original single track one, but the latter is excellent at performing many editing task for single tracks of audio.. For a lesser price range, although Power tracks is a great value for the money, I'd easily give the nod to N track for it's relative wealth of features at it's modest price and for it's ease of use. Cakewalk Express is also inexpensive and does a good job I have or have had 'em all.
I used to mix solely on my boards too, and for demo's I sometimes still do, but when I get a litle more serious about it, I find that I can do a better job by editing and mixing individual audio tracks. With N track, you have either option at your disposal.
