I like to use Sonar 5 Studio Edition, it only cost me £60, and it's amazing! I use it with my M Audio 192 card, and (for now) a tapco mixer. I plan to upgrade to a Mackie Oynx desk soon though.
Prefer Sonar much more than Cubase, Logic, Pro Tools or any other I've tried, because you get unlimited tracks, fx and it has 64 bit proccessing, and a Lexicon Reverb plug in that really is proffessional quality. Compare the specs of Sonar to any other DAW out there.
The choice is yours in the end.
